. 2.5.53-mm2 was a bit sick in the timekeeping and slab department. That
should be fixed here.
. The idea of using the slab head arrays for object preallocation has been
abandoned. It involved too many slab changes, and slab just explodes in
your face when touched. So I've used a custom reservation pool in the
radix-tree code instead.
. I've spent two days chasing the memory leak which Con has reported and
have thus far not been able to reproduce it (managed to collaterally
discover a swapoff lockup and an htree leak though). It's probably an
ext3/VM interaction. Please keep an eye out for this.
Changes since 2.5.53-mm2:
-aic-bounce.patch
-ga2.patch

reasons. Is needed to avoid a shared pagetable deadlock.

2.5.54-mm1 is at
http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.54/2.5.54-mm1/
it is identical to 2.5.53-mm3.

Failed while booting up.
It executed mem_init()
Then during execution of kmem_cache_sizes_init(),
It created generic caches.
After that following error came,
Invalid operand: 0000
...
Unable to handle kernel paging request at virtual address b08e3fef

Please enable "Load all symbols for debugging/kksymoops" in
the "Kernel hacking" menu and send a full report.
kksymoops is a bit broken in 2.5.54. You may need this patch:
