Subject: kernel BUG - handle_mm_fault - Ubuntu 14.04 kernel 3.13.0-29-generic

Hi, can someone please take a look at this and tell me what is going on?

The event log reports no ECC errors.

This machine was working fine with an older Ubuntu version, and has
failed this way twice since an upgrade 2 weeks ago.

Symptoms include:
 - load goes up high, currently 1872.72
 - "ps -ef" hangs
 - this time I tested "echo w > /proc/sysrq-trigger" which made the
local shell and ssh hang, and ctrl+alt+del doesn't work, but machine
still responds to ping

Please CC me; I'm not on the list.

Thanks,
Peter
