It did come through, and I replied ;)
The below post-2.6.23-rc1 patch should fix it.
commit b8c1c5da1520977cb55a358f20fc09567d40cad9

slab: correctly handle __GFP_ZERO
Use the correct local variable when calling into the page allocator. Local
`flags' can have __GFP_ZERO set, which causes us to pass __GFP_ZERO into the
page allocator, possibly from illegal contexts. The page allocator will
later
do prep_zero_page()->kmap_atomic(..., KM_USER0) from irq contexts and will
then go BUG.
