Subject: wierd bug, help decoding sysrq output?
Date: Mon, 19 Feb 2007 15:12:53 -0600 [thread overview]
Message-ID: <45DA12D5.6090905@nortel.com> (raw)
I'm looking for some help decoding an x86 stack trace.
We have a process showing as defunct, but its parent is listed as init.
It shows up in top as using basically 100% cpu, and one cpu out of
four is showing spending all its time in "sys".
Dumping all tasks via sysrq gave the following information for the
affected process:
oamFmLogServe X C8A5E610 0 23551 1 23553 20706 (L-TLB)
ee45fe58 00000046 c8a5ebf0 c8a5e610 00000a3c 00000000 00000003 c04cfb74
f91a919f c01406ce c8a5ebf0 00000000 c8a5e610 c515c060 00000001

00000020
Call Trace:
[<c011e742>] do_exit+0x31e/0x48a
[<c011e95e>] do_group_exit+0x3a/0xa9
[<c01277d1>] get_signal_to_deliver+0x21f/0x342
[<c010238a>] do_signal+0x72/0x12f
[<c0102482>] do_notify_resume+0x3b/0x3d
[<c010265e>] work_notifysig+0x13/0x15
Disassembling vmlinux gives:
0xc011e73d <do_exit+793>: call 0xc046194c <schedule>
0xc011e742 <do_exit+798>: ud2a
I haven't been able to find any kernel code that would match up to a
program counter of "C8A5E610".
Anyone have any ideas?
Chris
