I haven't tried that, partially to get rid of the initrd and have
drivers for the controllers/disks in-kernel, partially because I like
having built my own kernel. That might be silly, of course - I can try
the Debian kernel, if you think it would make a difference.

I am now running with all lock debugging turned on. "Unfortunately"
the machine has been running stable since the crash last weekend -
perhaps the extra-large backup rourines at sunday may trigger it
again...

Hopefully lock debugging will tell.
