Re: SCSI problem, can't instal Debian
Just fyi, I think I finally did fix my SCSI problem (had a 1 in 3 chance
of booting without the infinite reset errors). The problem was that I
have a device that was incorrectly set to UW instead of U (40 max trans
rate, instead of 20). The old aic7xxx driver I had in RH4 somehow didn't
have a problem with this, it would simply renegotiate transfers to the
correct speed... I changed the setting in my adaptec card, rebooted with
the aic7xxx=extended,no_reset flag, and all's well.
