Apparently not. Fingers are pointing at md/raid1 - with reasonable
cause - but I cannot find any error in that code, not can I reproduce
the problem.
Are you able to narrow down the difference between working and
not-working.
Possibly use 'git bisect' (This is the best option, but not having
used it myself yet, I don't feel comfortable recommending it).
Possibly just try the various 2.6.15-rcX kernels and find the first
one that breaks.
That would be a great help.
