Coda File System

kernel BUG at inode.c

In addition to the problem with my coda-server I just encountered another

I decided to give ext3 on my laptop a try and made a new 2.4.9 kernel
with the patch from this URL:

I changed my lilo.conf accordingliy and booted the new kernel without
having switched any to of my partitions to ext3, just the new kernel with
ext3 support. Everything seemed fine for the first few seconds but then I
get this error on my console:

I know that those lines are specific to my system and you won't be able
to make something out of it. So please tell my what I have to do to help
you. Are there any known problems with coda and ext3 support?

ps ax still showed the venus process, but the partition was not mounted
and the system could not be stopped cleanly as it hangs while "Unmounting
file systems" (I'm glad to have compiled SysRq into my kernel. :-) )

Attached is my venus.log. Let me know if you need further information.
