[parisc-linux] 2.6.15-rc5-pa2: "BUG: soft lockup detected on CPU#0!"

[Helge Deller]

Hello,

2.6.15-rc5-pa2 boots on all my machines (715/64, B160L, C3000) with the 32bit kernel, but on the B160L I see the 
BUG: soft lockup detected on CPU#0!
message below.
Any ideas ?

PS: The message seems to be more informational, since the kernel still boots up fine.
