Hi,
I am using the 2.4.22-1.2197.nptl_51.rhfc1.at kernels, which are RH's
latest errata kernels for FC1 with xfs 1.3.1 patched in (and some
other less relevant patches). Another oops was one stack level deeper
in _pagebuf_find.
Is this a known bug of XFS 1.3.1? If yes, when does it trigger, and
how can I avoid it in the future? And finally: the oops caused some
httpd processes to get stuck in D state. Is there any other way to get
rid of them other than rebooting - rebooting when xfs oopses that way
is not possible, only hard power-cycles :(?
Thanks!
