SubjectRe: 2.6.12-rc5-mm2
Hi Andrew,

I'm encountering the following annoying bug messages in 2.6.12-rc5-mm1
and -mm2 that I can't reproduce in 2.6.12-rc5 with the sym53c8xx_2
SCSI driver. I don't use the SCSI card/drive for booting but the
driver is compiled into my kernel, and reading from the drive seems
OK. Booting -mm2 I get the following :
