Description of problem:
The aic7xxx module does not see an installed CDROM. The system is a PII-
400 w/ an AHA2940W controller. The SCSI BIOS sees the CDROM, but aic7xxx
does not detect it.
I've tried aic7xxx=no_reset and aic7xxx=ultra. I've tried driver disks
with aic7xxx_mod and aic7xxx_new. The drive works fine in the same
machine within Win98.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot from RH7.1 Install CD
2. Choose CDROM as source media
Actual Results: After choosing the a local CDROM, it asks for a driver.
But the aic7xxx driver is already loaded.
Expected Results: The aic7xxx driver should detect the CDROM
Initially, I installed via a network install, then tried to adjust the
module parameters. This still did not work. I got the patch from
http://people.freebsd.org/~gibbs/linux/ and applied it to the kernel. It
still was not detected.
Use of aic7xxx=no_reset resolves the problem. Perhaps the problem lies in the
reset. Since the Windows drivers work fine (i.e. it doesn't reset the SCSI
bus) and no_reset works, I've retracted the bug report.
