Public bug reported:
I'm using a karmic pre-release on x86-64, a Thinkpad X60.
I have an USB external hard drive connector, a Rosewill RU-DU100, that lets one
take a SATA drive and attach it over USB. It's listed in lsusb as:
Bus 001 Device 004: ID 152d:2329 JMicron Technology Corp. / JMicron USA
Technology Corp.
and when plugged in dmesg reads:

I was running IO against this drive (a mkfs.ext3), and pulled the USB
plug out. I happened to be on a terminal at a time, so I got to see a
long list of io errors get instantly dumped to the console. Then the
computer froze completely.
A minute later the console printed "BUG: soft lockup!" -- I don't have
the exact error message, but it appeared twice, once claiming CPU#0 was
stuck and once claiming CPU#1 was stuck, in both cases for 60 seconds,
and with a note in square brackets at the end about [udevd].
Unfortunately (though hardly a surprise) none of the errors made it to
kern.log.
While pulling out a working drive is hardly *recommended*, it should not
crash the computer.
