Hi,

The numbers in brackets [] are the timestamps of the messages, so
[ 2192.584002] means it's been about 2192 seconds since the computer has
booted.

This definitely sounds like a kernel bug to me, you might want to check
out <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/206316> or
file your own bug report with "ubuntu-bug linux". Thanks!
