this is not actually a regression in 2.6.25-rc*, as some 2.6.24-rc
kernel displayed the same problem. Unfortunately, it's a little tough
to automatically bisect as the oops happens intermittently. In the
other thread, though, Paul mentioned a patch which might fix the issue
was merged recently.

Kamalesh, any updates?

Hi Nish,

I tested the 2.6.25-rc8 kernel which already has the patch in it, but still the oops is reproducible.
The oops was reproducible in the second run though.
