Description Need Real Name 2001-09-27 02:15:24 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0b; Windows 98)

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):


How reproducible:
Always

Steps to Reproduce:
1. Boot from RH7.1 Install CD
2. Choose CDROM as source media
3.
	

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

Additional info:

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.
