Description of problem:
Installer halts at "aic7xxx loading"
AMD K6-2 300,128M, SiS 5591 chipset, Adaptec 7850 PCI SCSI (IRQ 11)with a
Plextor burner hanging on it, PCI Ethernet, PCI SB Live!,, 2 IBM hds,
Memorex IDE CD-ROM
Alt F4 yields cables are OK
<6> SCSI0 Adaptec AHA274x/284x/294x
<4> <Adaptec AIC-7850 Host Adaptor>
<4> Abort command due to timeout pid 0,scsi 0, channel 0,id 0, lun 02

last two lines repeat
I've tried 'linux ide=nodma'
Just flashed my bios, no change
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot off of IDE CDROM (located as secondary slave)
Actual Results: Hangs on 'aic7xxx loading'
Expected Results: Load the Adaptec driver and proceed
The HDs are IDE
Had the same problem for the first 2 very early versions of 2.4 kernel, when
the "old" aic7xxx driver was replaced by the new present kernel driver.
I had a Yamaha burner on it (threw it away 'n don't recommend it) with the same
result as you get.
Even worse; when rebooting my machine the burner disappeared from the setting
in the the SCSI-BIOS and I had to reconfigure the SCSI-bus setting.
Maybe you try the following: take out the power supply from the SCSI burner and
install RH 7.2 as you like it. Then compile your own kernel with the _old_
aic7xxx driver and install it, power down your machine, put again the power
supply to the SCSI burner and try to reboot your system. This worked for me
though I know it is not a brilliant solution.
Now I replaced my Yamaha SCSI burner by a much cheaper ATAPI one and it works
Try using the new aic7xxx driver on your system. To use it, boot the installer
with the option noprobe and then when asked about where your media is, answer
local CD-ROM, then when prompted to add a device, add a SCSI device and then
select the "New Adaptec ...." from the list (you will have to scroll all the way
down to the N's, don't select any of the Adaptec options listed in the A's
portion of the list). Report the results back here please.
Using the experimental Adaptec driver seemed to work and permitted a smooth
I installed all of the packages then rebooted.
Now, on boot up it hangs on "Entering Red Hat Interactive Press 'I' to continue"
I didn't notice any error messeges preceding this portion of startup.
It hangs right there every time. Pressing 'I' does nothing. Alt F-4 nothing.
CTL ALT DEL, nothing. Wait 15 minutes, nothing. Hard restart. Have not tried to
RH 7.2 installs and running works great if I just unplug the Adaptec card
before I start. But I'd like to use the Plextor burner it's attached to.
Thanks for the bug report. However, Red Hat no longer maintains this version of
