kernel BUG at lib/list_debug.c:27!

[h.verhagen.web104]

Hi,

According to dmesg, I encountered a kernel bug on my system.
I'm not sure if this is the appropriate place to report this problem
as this occured on a Fedora kernel. Maybe its a general problem?


kernel BUG at lib/list_debug.c:27!
invalid opcode: 0000 [2] SMP

 ===========================================
= What was I doing when this happened.
==========================================
I was   doing a  rm -rf   /media/somedir/   command  on a
USB harddisk.  This USB harddisk casing contained a flaky IDE
harddisk.  (smartd had been giving warnings about this drive for a
while, that it was about to break doing.

What happened.

The rm  stuck, (couldn't be killed, even with a kill -9 command).
dmesg showed a kernel bug.

Please file a bug at https://bugzilla.redhat.com/ under Product: Fedora,
Version: f7, and Component: kernel.

BZ#247975 looks similar, but I am not sure if it is the same issue.

Hope this helps.

Thanks,
Eugene
