I installed Red Hat Linux version 6.0 on Friday. Install went well. When it came time to reboot the scsi driver reported a timeout error, and said something to the effect of "Trying Harder" then went into a loop timing out and trying harder. When I selected the uniprocessor version from LILO it booted fine. System is dual pentium 166 MMX with 128 Meg of RAM and 2 SCSI driver. Booting from second drive, Swap on First.
Could you try the latest kernel in Raw Hide (2.2.11-4, or greater?)
