Twinkle call crash - list_del corruption
Last modified: 2012-11-20 06:54:28 EST
Description of problem:
Twinkle call on notebook Lenovo X220 crashes my host.
It is F-16 with F-17 kernel (offtopic: because F-16 kernels suddenly reboot for me once a day without any netconsole message).
Version-Release number of selected component (if applicable):
Tried Twinkle call twice, twice crashed.
Steps to Reproduce:
Make Twinkle SIP call.
Locked up machine, messages attached:
WARNING: at lib/list_debug.c:59 __list_del_entry+0xa1/0xd0()
Normal calls like with F-16 kernels.
The netconsole messages are somehow messed/corrupted, they repeat indefinitely so grabbed only some first 2000 lines of the dump.

Looks like the same problem as bug 871078 except F17/x86_64 rather than F16/i686: common pattern is list_del corruption with usb_hcd_unlink_urb_from_ep in the stack trace.
There's a fix built for f16/17/18 in bug 871078 that works for me. Closing this one as a duplicate.

Confirming kernel-3.6.7-1.fc16.x86_64 works for me with Twinkle.
