Package: linux-2.6

Severity: normal
In both the Debian and kernel.org 2.6.39-rc? kernels, I am experiencing
numerous "BUG: soft lockup - CPU#0 stuck for xxs!" errors where xx is
between 61 and 64.
could you check against newest 2.6.39~rc6 ?
This problem did not occur in 2.6.38 kernels.
Previous attempts at git-bisecting the kernel.org kernels have been
inconclusive.

thanks for your report.
Hi, I've had only one lockup using 2.6.39-rc6-git2 from kernel.org:

I've since installed linux-image-2.6.39-rc6-686-pae version
2.6.39~rc6-1~experimental.1 and will see if I get the same error.

Arthur.
