Description Vladimir Gendler 1999-10-15 17:21:18 UTC
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.

Comment 1 Vladimir Gendler 1999-10-17 05:24:59 UTC
Installation of RedHat LINUXes 5.x was without problems.

   Sincerely, Vladimir.

Comment 2 Jay Turner 1999-10-21 19:01:59 UTC
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.

    Sincerely, Vladimir.

Comment 3 Vladimir Gendler 1999-11-07 18:33:59 UTC
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.

Comment 4 Jon Meek 2000-01-03 03:17:59 UTC
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:

Comment 5 Vladimir Gendler 2000-01-03 16:25:59 UTC
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.

Comment 10 Doug Ledford 2000-10-03 19:54:50 UTC
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.
