Message-ID: <4198686D.8000301@yandex.ru> (raw)
Hello,
I've hit on bug in JFFS2, but I can not reproduce it easilly yet. I have
stess test which in general creates files, deletes them, creates
directories and deletes them, and so on so on. When I run this test
nightly, I see the following error when I come at work in the morning:

May be somebody may comment this without having the test which can
easilly reproduce this bug?
P.S. My kernel is 2.6.8.1, UP, Preemption is disabled.
P.P.S. I observed this several times.
