Adaptec 7880, Linux x86

Mon Nov 16 10:47:59 PST 1998

Hello,

I'm looking for advice on how to proceed installing RH5.1 on 
a Pentium system with an Adaptec 7880. I keep running into 
an infinite SCSI bus reset loop. I've tried the default 
RH5.1 boot disk, the boot.img file from Doug Ledford's ftp 
site (patch 10), and my own 2.0.35 kernel with patch 12 (
aic7xxx driver version 5.1.2/2.0.35).

Debug info follows:

Thanks,
