It's seems to be the same problem I have (see my posting from 5.1.2005
on this mailing-list).

The problem was reproducable. I changed to ext2, but problem persists.
I tried several kernel configurations (with a special extra-small
configuration, which had only the absolute necessary turned on), but
it had no effect (It only took longer to reproduce the problem).
I tried the kernels 2.6.9 with and without the -ac patches, wth no
success at all.

Because I'm not at home till 29.01., I could not run any tests at the
moment, but the problem seem to be the same. The seems to be no problem
with the 2.4 kernel series.

Any ideas?
