I am runnig Red Hat 4.1, and have an onboard Adaptec 2940.
(it is actually called the 7850 because it is onboard)
When I recompile my kernel and reboot with the new kernel,
it gets to the SCSI init phase, and a line of garbage starts scrolling continuously accross the screen, it will stop, retry the device, and do it again. The scrolling message is something like 10.0mhz sync buf....

Sorry I cannot elaborate further at the moment, this was a few weeks ago. I someone can help me out, I can post further information.

Thanks,

Well, it is Red Hat 4.1, I believe the kernel I was compiling was 2.027 or something near that. I must boot into my Linux partition to check..

What kernel version?
there have been some glitches in the 2940 series driver (adaptec hasn't been alltogether cooperative at times with programming information)

Edited text of question
I have two suggestions:

1) Try booting with the extra option aic7xxx=no_reset (or something like that, check the UG)

2) If your BIOS boot sequence offers it, go into the SCSI setup
utility and set the parameters to the most unadventurous set you can come up with (disable FAST and WIDE, for instance). If that works, you can add features one by one until you find the trouble.
