Had two of the above crashes tonight, both produced core files ... fsck appears
to run well in both cases ... a few UNREF FILES, some INCORRECT BLOCK COUNT ...
but, no manual fsck required, so "clean" ...
Trace from one of the cores is as follows ... its a fairly old 6.1-STABLE
(Jun26th), but just figured I'd post in case this is in the least bit useful
... have saved both cores if I can provide any more details ...
