hmm.

I don't think so. BackupPC opens a UNIX domain socket on startup (and failing to do that is a fatal error).

Hmm. You might simply have put it elsewhere (probably under /var/log). But I find it confusing that ... > So cpool has today's date ... but ... > ]# ls -l /media/disk/cpool > [...] > Nothing since 6/28. Why is ctime on cpool/ updated when all subdirectories already exist? Hmm, probably the hardlink test (which does *not* necessarily mean this is the cpool BackupPC uses - again: which version are you running?). In any case, pool files would be created three directory levels below. > This is where I got to when the machine crashed.

But user space processes can't cause kernel panics (they can maybe trigger them, but never *cause* them). I'm no expert on kernel stack traces, so I won't guess about the cause. If I were you, I'd check the BackupPC pool file system (and maybe system memory). > This is repeated for the 2nd CPU. Does this have anything to do with > that link we created?

I've had more problems with older kernels and USB2 than I could have wished for, but newer kernels seem to behave much better. Still, I'd try to avoid USB for such heavy use as a BackupPC pool tends to be. Is that at all possible? eSATA?
