I'm finally through compiling all kernels between the last good and first bad
one (slow hardware sucks ;) ) -- the problem was introduced in the patch from
2.6.16-rc5 to 2.6.16-rc6, and is apparently not present in any -mm releases
before 2.6.16-rc6.
I'll try to isolate which change between 2.6.16-rc5 and -rc6 causes it... But
it would be nice if someone who knows a bit more about the code involved
could look at it.
