Red Hat Bugzilla – Bug 36358
[aic7xxx] System hangs with Adaptec 7890 on-board SCSI controller and add-in QLogic QLA2200

From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3 i686) At boot time, as the aic7xxx driver loads it hangs the machine. It only does this if the QLA2200 card is present in the system. If the no_probe option is passed to the aic7xxx module or if the QLA2200 is absent, everything works correctly. Reproducible: Always Steps to Reproduce: 1. Attempt to install Red Hat Linux 7.1 on a machine with on-board Adaptec 7890 SCSI controllers and a QLogic QLA2200. The system will lock when the installer loads the aic7xxx driver. This can be avoided by using the "expert noprobe" install mode. 2. Reboot the machine. :-) Actual Results: System lockup requiring a system reset. Expected Results: The drivers should co-exist wihout causing system lockups. This is using the 2.4.2-2boot and 2.4.2-2smp kernels from Red Hat 7.1 retail CDs. The machine is a Dell PowerEdge 6350 with 2 500MHz Pentium III Xeon processors and 1GB of RAM. The install target is an 18GB hard disk on the first on-board Adaptec 7890 SCSI controller. This has also been seen on a quad-400MHz machine with 1GB of RAM.
FYI, I think this is probably related to, or a duplicate of bug 29572.
I just received red hat 7.1 ... having the same problem ... cannot install the product successfully... it is really annoying since i am going to teach a class, and planned on using 7.1 ... need a fix asap!
just tried many ways to get the product installed. it doesn't work! several other bug ID's exist that sort of identify the same problem in one or more ways. i spent the whole afternoon trying to get it loaded. yup, there may be workarounds (please let me know exactly if one works using the distribution). i think this bug should be raised to a higher priority ... the product (Deluxe Workstation) does not install out of the box! I do not think this is a good situation. i have installed 6.1, 6.2 and 7.0 hundreds of times in class, and there have been no major issues. I do not think 7.1 should have been released in this state. Would like to have some idea on when this will be resolved and if new distribution will be made available.
I just bought 8 VALinux "fire sale" systems.. I have to use 6.2 on them, b/c 7.1 hangs on this exact problem... :(~~ Any clues on a fix?
When installing, at the boot prompt, enter "expert noprobe" to install in expert mode. When you choose the "aic7xxx" driver, pass "aic7xxx=no_probe" parameter option.
You can also avoid the problem by loading the QLogic driver before the aic7xxx driver. However, there isn't really a fix to be made here except to use the aic7xxx=no_probe option because the problem really is that the PCI BIOS is assigning an address to the QLogic card that overlaps with the addresses that EISA or VLB based aic7xxx cards *could* be at and as the driver is probing for those addresses, it is causing a system lock. Simply moving the QLogic card to a different slot on a different peer PCI bus could be sufficient to make the problem go away entirely. I'm marking this as WONTFIX because A) the aic7xxx driver is not deprecated in favor of the new aic7xxx driver from Adaptec and any fixes should be there, not in the old driver and B) the only way to fix this would be to force the aic7xxx driver to try and interpret the address registers on *all* PCI devices looking for conflicts between them and the built in EISA/VLB bus probe addresses it uses, and since those address registers on different PCI devices are used differently depending on the PCI device in question, this would likely be a doomed attempt at sorting them all out.
I have the same problem on a Intel L440GX+ Serverboard with Adaptec 7896 on- board SCSI . The Installer hang with "aic7xxx driver loading". I tried to do the expert install with the "aic7xxx=no_probe" as parameter for the adaptec controller. It didn't work. The Installation of red Hat 7.0 worked fine.
just wondering why everyone is going around in circles on this still when the install issue has been resolved in bug 29555. my question: is this problem fixed in the regular "store" distribution, or is it expected to be fixed in the next release (7.2?).
