Red Hat Bugzilla – Bug 5994
Infinite loop resetting AHA-2940 during install
Last modified: 2008-05-01 11:37:52 EDT
At the step of loading aic7xxx for Adaptec AHA-2940U/UW install hangs on. ALT+F4 shows timeout on CD-ROM quering and endlessly resets the SCSI. Hard drives look fine. This problem exists for both versions 6.1 and 6.0. AHA-2940 BIOSes tried were 1.34.3 and the lates one - 1.20.0. This problem was verified on other machines with different modification of AHA-2940. Install with parameter aic7xxx=no_probe did not help. The installation goes fine for Ultra2 AHA-2940U2W. Sincerely, Vladimir.
Installation of RedHat LINUXes 5.x was without problems. Sincerely, Vladimir.
Please send cat of /proc/scsi/scsi and full dmesg from boot with working version of driver on Ultra II and 6.1 and the developer will try and determine why it is failing on UW controller. ------- Additional Comments From 10/21/99 22:33 ------- I got an email requesting some additional information and here is my respond, just in case to keep the history here. ==================================================== Hi, I have not installed this version on the machine with 2940U2W. I only tried to pass that point where it breaks on 2940UW and it went OK. I am planing to install on the machine with 2940U2W later on. By the way, Caldera Open Linux 2.3 has exactly the same problem.

Hi, This is new information about the installation of v6.1. Probably it should be a new bug. I was trying to instal this version on PC configured as: Motherboard: SE440BX-2, SCSI card: Adaptec AHA-2940U2W, CPU: Pentium III 450 MGz, RAM: 128 MB DRAM ECC P100, AGP Video card: Matrox Millenium G400 with 32 MB of video RAM Sound card: Creative Labs SoundBlasterLive!, Two Seagate Barracuda SCSI LVD hard drives 9 GB, Toshiba SCSI 40X CD-ROM, ViewSonic PT775 monitor. All BIOSes are the latest. As I wrote in the first report it passed the SCSI devices recognition succesfully. Then I selected needed packages and came to the point where all packages got installed. It took about 5 minutes only. Then the system was silent for about 5 - 6 minutes and then the pop up window appeared informing about post installation tasks. Here is the point where system went nowhere. I was waiting for about 20 minutes. Another strange things is I have a pretty powerfull video card with 32 MB of video memory and a very good monitor. However the best I could get for X windows was 800x600 resolution with 16 bit colors. I managed to install Caldera distribution without any problem at all. During this installation I had a choice of a huge number of monitors with my, of course, included. For my monitor the selection 1280x1024 with 32 bit colors worked perfectly giving me 91 Hz refresh rate which I could even achieve neither for W98 nor for Windows NT. Interestingly to point out that this video card Millenium G400 was not among supported ones by Caldera OpenLinux 2.3. The best what they support from Matrox was Millenium G200. However the installation program corretly recognized the Matrox video chip set and worked at the highest resolutions and colors producing excellent refresh rate as stated in the specification for this monitor. Sincerely, Vladimir.
I am having a similar problem and it seems that it has something to do with LVD drives. Both 6.1 and 6.0 fail to install when a LVD drive is connected to the 2940U2, but 5.2 installs without incident on the LVD drive (and it was the fastest Linux install I have ever seen). Here are details that might be helpful: Dell Precision 210 MT workstation One PIII/600 CPU (it is a dual CPU capable motherboard) Adaptec 2940U2 (OEM) BIOS 2.20.0S2 NEC Fast/Ultra-SE CDROM Fujitsu MAG3091MP Ultra2-LVD 9GB disk The problem is that when the Ultra2-LVD disk is plugged-in the aic7xxx driver does not load. Apparently it never gets a response from "Test Unit Ready". I can boot from the CDROM on the Fast/Ultra-SE bus though. I was able to install RedHat 6.1 on an external Fast/Ultra-SE disk (with the Ultra2-LVD disk unplugged). I then built two newer uni-processor kernels (2.2.13 and 2.3.34) but the system would never boot as long as the Ultra2-LVD was plugged in. I tried the driver parameters: aic7xxx=extended and aic7xxx=no_probe with no luck. Many BIOS settings were tested as well. I also tried RedHat 6.0 which seems to fail in the same way as 6.1. As mentioned above 5.2 has no problem. Here are /proc/scsi/aic7xxx/0, /proc/scsi/scsi, and dmesg output from 5.2 with the LVD drive, and from 6.1 with a slow, single width drive: ----------------------------------------------------- RedHat 5.2 Information (working config with LVD drive) cat /proc/scsi/aic7xxx/0 Adaptec AIC7xxx driver version: 5.1.2/3.2.4 Compile Options: AIC7XXX_RESET_DELAY : 15 AIC7XXX_TAGGED_QUEUEING: Adapter Support Enabled Check below to see which devices use tagged queueing AIC7XXX_PAGE_ENABLE : Enabled (This is no longer an option) AIC7XXX_PROC_STATS : Disabled Adapter Configuration: SCSI Adapter: Adaptec AHA-294X Ultra2 SCSI host adapter Ultra2-LVD/SE Wide Controller PCI MMAPed I/O Base: 0xfe000000 Adapter SEEPROM Config: SEEPROM found and used.

Hi, This is not a problem with LVD drives. 1. This installation failed on the old AHA-2940 U/UW. I have checked this for two configurations, one - with all narrow, another - withh all wide drives. I have checked this for two distributions - RedHat and Caldera. It indicates that the problem more likely with the driver aic7xxx. So shows messages from RedHat - infinite loop while trying to reset SCSI CD-ROM. I do not know how to see messages from Caldera but almost positive that they will be the same. 2. In case of AHA-2940 U2W with LVD drives the installation behaves differently. I managed to install Caldera, so, it means that aic7xxx is OK for LVD drives! RedHat failed on post installation tasks, passed the SCSI CD-ROM recognition successfully. It seems that we have two problems now. First - aic7xxx does not work with (at least) AHA-2940 U/UW but works with AHA-2940 U2W with LVD drives. Second - RedHat installation program has a bug somewhere in its post installation tasks. Sincerely, Vladimir.
I had the same problem with a Dell Workstation 210 MT with the Adaptec 2940U2 and the same Fujitsu MAG3091MP. Problem was solved by loading the latest <http://people.redhat.com/dledford/dd.img> which seems to be 5.1.27. With that change, RH6.1 installs cleanly.
I tried to install using the latest dd image as you adviced but it did not help. The installation still hangs on the postinstallation tasks. By the way I managed to install Mandrake LINUX. Sincerely, Vladimir.
Install RedHat 6.2 on PC with AHA-2940U2W without any problems. Tried to install it on PC with AHA-2940 W/UW. Still the same problem - endless loop on CD-ROM. Sincerely, Vladimir.
Seeing exactly the same problem with AIC-7896 controller on ISP 2150. Works fine with SE Drives, fails with Seagate Cheetah ST39204LC, even when forced to single-ended mode.
There are two different bugs being reported here. One, there was a bug with the aic7xxx driver and some LVD devices. It depended on whether or not the LVD drive tried to do preemptive speed negotiations. When they did, the aic7xxx driver would fail. That has since been fixed in later aic7xxx driver versions. The other bug, the one related to the CD-ROM drives, isn't likely to be an aic7xxx bug, it's likely the fact that Red Hat 6.1 would try to probe all luns of any device found on the SCSI bus and some devices would lock up when you did so, which rendered the SCSI bus unuseable. Since both of these situations have been corrected in the latest release, I'm going to close this bug. If you still have problems with the latest released software, then please open up a new bug based upon the results of trying to use the latest software.
No, it is not resolved. The origonal problem repported here is still the same in all RH versions - 6.2 and 7.0. My PC has only one SCSI card. I tried this on other configuration (with differend CD ROM) - the same result. It ha snothing to do with LVD drives. With LVD drives (important 2940 U2W) it is OK. It fails for 2940 U/UW. Take any PC with this card and you will see this problem. Sincerely, Vladimir.
