Andrew,
There is a problem in 2.6.9-rc1-mm5 related to the reiserfs handling of ACLs. Namely, if a reiserfs partition is mounted with "-o acl", any attempt to create a file on it results in an Oops similar to this one:

This happens 100% of the time, and the workaround is not to mount reiserfs with "-o acl", of course.
Also, in the output of dmesg I've got the following line:
udev[10682]: segfault at 0000000000000138 rip 0000000000405818 rsp 0000007fbffff470 error 4
(this does not seem to be reproducible, however) and the following error message from the USB subsystem:
usb usb2: string descriptor 0 read error: -113
(repeated 8 times, occurs always at startup).
The kernel is booted with the following command line: root=/dev/hdc6 vga=792 resume=/dev/hdc3 pci=routeirq nmi_watchdog=0 console=ttyS0,57600
The .config is available at: http://www.sisk.pl/kernel/040913/2.6.9-rc1-mm5.config
