I tried 2.6.26-rc1 (actually about 50 commits past -rc1 as pulled
from kernel.org this morning) and could not reproduce this.

I was using the pstack(1) that shipped with Redhat EL4.5

I ran thousands of "pstack $$" with the system:
1) idle
2) busy (running kernel build with make -j16)
3) swapping (running hackbench)

and did not see the "BUG: sleeping function" message.

So Seto-san is off the hook (his patch is definitely in -rc1).

This is probably some other patch in -mm ... unless there is
something different about your .config. Do you have PREEMPT
enabled (or anything else that looks "interesting" for this
problem)?
