As an extra data point, i have:

# cat /proc/scsi/scsi

vermagic: 2.6.6-1.397.root K6 REGPARM gcc-3.3

And am not having (touch wood) any stability problems using these
disks with linux md RAID1 and RAID5. Though, they're in a K6-II 350,
so performance is slow anyway. (i get about 25MB/s absolute max
reading from a RAID-5 array).
