Ah... interesting... I had a funny that appeared to be a corruption
in the buffer head lists (or might not have been). This is a system
with 7 SCSI drives, a couple of tape drives, 2 DPT controllers and
a future domain, 3 RAID groups of two drives. It appears solid
even under the most extreme load. When the error occurred I had
just been playing with mt, doing multi-file backups to an Exabyte
(which is also solid normally). mt does ioctls. That's all it does :-).
N.B. I'm using the eata_dma driver for the DPTs. Previously I
tried using the other eata driver but that seemed to trash itself
under load (both RAID1'd and normal partitions) - *very* heavy
load that is. I had tagged queuing etc. turned on. I didn't try
turning it off. Not much chance of trying it at the moment :-).
I think this was a driver problem where as the above is likely
higher level. Maybe.
