There are SCSI issues with the 2.x and 3.x kernels. On my R5000
Challenge S, I found that an old Seagate 1GB drive would work but any
other drive that I tried resulted in a boot failure due to SCSI errors.

The SCSI problem was fixed in -current around September / October last
year and I have successfully run a kernel built from the 9th November
snapshot on my box. A 4.0BETA kernel from early January (after the
re-branch) also booted OK.

I haven't tried a more recent -current kernel so I don't know if the
cache error indicates a new bug or not. AFAIK, older kernels (pre 2.0 ?)
didn't use the L2 cache so there is a possibility that a cache hardware
fault wouldn't have been detected in 1.6 but would show up in a more
recent kernel.
