The bug bit me today, after I pulled out a mounted ext3 usb drive.  A total
Kernel hang.  Video still displayed.  No ping.  No mouse.  No keyboard. 
Unfortunately I forgot about Magic SysRq
(http://en.wikipedia.org/wiki/Magic_SysRq_key ) and did not probe.  Here's all
I got:

# vi /var/log/syslog
Jul 13 00:31:43 ubuntu kernel: [181916.094245] JBD2: I/O error detected when
updating journal superblock for sde1-8.
Jul 13 00:40:49 ubuntu kernel: imklog 4.6.4, log source = /proc/kmsg started.

# uname -a
Linux ubuntu 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011
x86_64 x86_64 x86_64 GNU/Linux
