I backported these changes to a netbsd-2-0-RELEASE kernel. It didn't help for
It paniced again while the amanda client was running.
If you think that a current kernel has additionnal fixes that may be relevant,
I can try a current kernel.
Also, I also have a dual-CPU sparc10 with a similar workload (several mrtg
processes, apc UPS on serial port, amanda client) which never show this
problem, so it may be a i386-specific issue.
