  BUG: soft lockup - CPU#1 stuck for 61s! [kvm:19760]; RIP:
  0010:[<ffffffffa0482ee0>]  [<ffffffffa0482ee0>]
  kvm_write_guest_time+0x180/0x1b0 [kvm]

Status in linux package in Ubuntu:

Bug description:
  Happening sInce some time after beta1 (I stopped running KVM for a
  while after the beta1 tests were done). Running kvm (via testdrive)
  against the ISOs.

  Almost always my laptop will hard-freeze. The screen is still painted
  under X, but no keys work. I cannot shift to a vTerm, and cannot use
  the magic keys to release from X. SSHing from another system fails (no
  route/response to/from host). Already established SSH sessions will
  not respond.

  All in all, it really sounds like a back kernel panic. The only option
  is to cycle power, wait for fsck to finish, and start again.

  On the few times I do not get a hard-freeze, a running KVM will
  suddenly display on the terminal header "QEMU stopped". After that,
  ending this KVM run and starting a new one will have KVM unable to
  recognise the guest vdisk (just-created/formatted). Rebooting returns
  KVM to work -- until the hard-freeze.

  This has happened today about 20 times. I have been unable to find
  anything in the logs pointing to an error, so far. Will now boot the
  -16 and -18 kernels to see if it is reproducible there; will also try
  a vanilla kernel.
