Hi!
Anybody else seeing frequent kernel panics in refile_inode (called from __remove_inode_page, called from shrink_cache) on 2.4.22-1.2188.nptlsmp?
I've filed a bug report in Bugzilla, if you experience similar panics you could help tracking it down:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=123332
There's also a bug with exactly the same symptoms which the Redhat guys claim to have fixed in 2.4.22-1.2190 test kernel update, but in my case the panice still occur.
The text of panic usually looks like this (the top of call trace look always teh same, down to the function try_to_free_pages_zone):
Unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c01691ae *pde = 0e723067 *pte = 00000000 Oops: 0002 e100 iptable_mangle ipt_REJECT ipt_multiport ipt_state ip_conntrack iptable_filter ip_tables floppy sg microcode keybdev mousedev hid input usb-uhci usbcore e CPU: 2 EIP: 0060:[<c01691ae>] Not tainted EFLAGS: 00010246
