2.4.18-pre7 - known issue with ext3?

2.4.18-pre7 - known issue with ext3?

[Raphael Manfredi]

I've got the following panic trace on the console this morning:

 invalid operand: 0000

	[ext3_file_write+67/76] [sys_write+142/196] [system_call+51/64] 

Are there known problems with the implementation of ext3 on this kernel, or
is the root cause elsewhere, and it's only an accident that it was in ext3
code at the time?

Something corrupted a buffer-head from your freelist.

Please send me your .config and a description of the hardware.
Also a description of what sorts of things the machine is
being used for.  Also please run memtest86 for 12 hours or
more and let me know the results.

Thanks.
