2.4.23 && md raid1 && reiserfs panic

Hello all,

Can someone point me towards the right mailing list to help get this 
issue resolved; I think I've hit something in either the MD, block or 
reiserfs sections, but I could be completely wrong.

The symptoms: rm a file from a working RAID1 md reiserfs filesystem, 
and I get a panic, rm(1) segfaults, and all further I/O to any interactive 
shells stop. The entire system is rednered incapable; reboot (via 
ctrl-alt-del) doesnt shutdown and the only action is to hard reset the box.

Attached is a copy of the oops as recorded by syslog, the script I run to 
start the error. The exact line that Segfaults is the rm() on a 2.2 GB 
tar file.

For reference, the system is documented at 
	http://www.james.rcpt.to/programs/debian/raid1/

This is only using the Debian packages of the kernel. 
kernel-image-2.4.23-686_2.4.23-1.

If there is any further info I can send, please let me know.

Please CC me as I am not subscribed to LKML. Ta.

Regards,
  James
