Because of the notification-daemon-bug I can't exactly say, when it happend.
I think it was during my rdesktop-session.

Unplugged a USB thumb drive without unmounting it first.
Comment 3 Dave Jones 2011-06-07 16:48:45 UTC 
what is this module ?

wl(P)

can you reproduce the bug without having this loaded ?
Comment 4 scd 2011-06-07 20:26:21 UTC 
Yes -- the wl module is from the kmod-wl module (needed as plain FC15 does not support the WLAN NIC of the Samsung 900X3A).
rmmoding wl and rebooting reproduced the bug (see next entry generated by abrt-gui).
Comment 5 scd 2011-06-07 20:27:59 UTC 
Sorry abrtd could not track the panic, but the backtrace looked the same as above.

I'm really not sure what happened.
Comment 7 Sebastian Krämer 2011-06-12 13:29:56 UTC 
I got this one too.
Happened with a USB stick, mounting in Thunar, folder won't come available for writing somehow. Don't know when or how exactly the kernel error occured.
F15 with current/updated kernel.
