Description of problem:
When trying to install RHEL4 on a machine with an Adaptec 2940 Ultra SCSI adaptor the install program freezes for a long time (over 10 minutes) on the 'loading aic7xxx module' message.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot off RHEL4 final release CD1
2.Press enter at RedHat boot prompt to accept default options (GUI install etc.)
Actual Results: The install froze for well over 30 minutes. Ctrl+Alt+F2 etc allowed switching between consoles. After an extended period of time the installer continued and RHEL4 installed correctly.
The last few lines on the Alt+F3 console were:
loaded e1000 from /modules/modules.cgz
loaded aic7xxx from /modules/modules.cgz
loaded libata from /modules/modules.cgz
loaded sata_sil from /modules/modules.cgz
loaded ata_piix from /modules/modules.cgz
Expected Results: The installer should have immediately loaded the aic7xxx driver and proceded with the install - it should only have taken a few seconds.
Just tried it again - the actual time taken to get past the 'loading aic7xxx'
was 50 minutes!!! (+-5mins) and that was with passing the option 'linux
acpi=force' at boot time.
I saw something very similar happen myself once, and the problem went away with
a system BIOS update. Can you check you have the latest from your vendor ?
I'm using a Tyan Tomcat i7210 S5112 mobo. It has the version 1.04 bios which is
the latest that was on the tyan.com website.
I just updated my BIOS after reading this and the problem went away for me.
I've got an Intel SCB2 in an RS2200 chassis. When it was hanging before, I got
a message that said something like "Disabling IRQ interrupt 10".
While installing AS4 on an IBM IntelliStation (onboard AIC7899), I can reproduce
the same error.
When you were able to install RH just with some delay, I think you don't have
any SCSI devices on the Adaptec!? I've waited more than half an hour and could
see on another console (Alt-F3) that the system tried tu scan the SCSI IDs with
reporting an error on each ID "no response, can't reset, exited with error code
02x220,...". Even when the machine has booted after this torture, I hadn't any
SCSI drives to installl RH on!
Today i'll check the BIOS version again, but I think, it's already the newest
Maybe you have some tricks for me, how you solved the problem if you couldn't do
a BIOS update!?
Thanks in advance
The kernel option 'acpi=off' should solve this problem...
