On this machine (Athlon 64 X2 4600, 4 GiB memory, lots of disks),
2.6.23-rc1-mm2 runs fine. 2.6.23-rc4-mm1 reproducably dies within seconds of
starting
a rsync session on another PC against this machine.

NULL pointer dereference
code:	nv_napi_poll+0x108

The dmesg you posted below doesn't cover the messages from this oops
itself. As you mentioned you can reproduce this oops easily, please do so,
and post the *full* oops log (if it doesn't get logged to disk, you can
try taking digicam photo, or write down *all* the messages and post here).
I built an x86_64 kernel as per your .config, but don't see any memory
dereference at nv_napi_poll+0x108 -- could be toolchain differences.

There are 4 pictures of oopses here:

image quality, well, they're readable.

Good luck,
