I thought about it. Given the drives are giving write errors when I write to /dev/md1 and not giving
write errors when the raid is stopped and I write to the individual disks then it *must* be some
issue with the hardware drivers.
If the block layer can submit a block to the driver that causes the drive to error out, then it's
really a fault of the driver for trying to do something illegal.
Anyway, I have done a clone of the libata-2.6 bk tree and I'm trying to figure out how to extract
all the individual csets between 2.6.6 and 2.6.7-rc1 so I can back them out 1 by 1 and see what
caused the problem.
My other tack is to enable full SCSI debugging and compare the trace from 2.6.5 and 2.6.7-rc1 to see
what is different.
I will give your suggestion a try when I get home tonight and fire it up on the extra promise channels.
Can anyone point me to a dummys guide to regression testing with BK? I read a great one by the WINE
guys years ago on regression testing by date with CVS and it has proved immensely helpful over the
years.
Regards,
Brad
