*** Bug 144590 has been marked as a duplicate of this bug. ***

Comment 3 Dave Jones 2005-01-09 00:50:47 UTC
will be fixed in the next build.  This was caused by an incompatability between
two debugging patches being enabled at the same time.


Comment 4 taj 2005-01-10 02:02:28 UTC
Just confirming that the fix works. I ran into the same issue with 1074.

Build 1075 does indeed appear to solve the problem.

Updated patch for slab object scanning

The problem was the combination of CONFIG_DEBUG_PAGEALLOC with some new code
that tries to scan all slab objects in the system. Some were unmapped, and that
crashed.
Attached is an update to the patch that does the scanning. It skips potentially
unmapped objects.
Patch vs. 2.6.11-rc6.
