Bug description:
  Hi

  About every 7-10 days I get a soft-lockup bug. Each time the bug apears, three processes gets locket at 100%. Every time its kswapd and two perl processes. Last time i tried to boot with no swap-partiotion. But that didn't help.

  I have also tried the 2.6.24-18.32 kernel. So it looks like this is
  not the same bug as
