This would lead me to point to the drivers for, as well as the hardware of, your RAID controller for possible problems.
The last time I came across similar issues, it has been, in one case, a power supply unable to quite keep up, causing such flakiness when all the drives were engaged, and in another case, RAM that ultimately tested bad. I wouldn't necessarily rule out a bad kernel build, but BackupPC (and other userspace programs) shouldn't be capable of crashing the kernel -- the key element of BackupPC is that it stresses a filesystem. > Hi people, > > OK I've tried swapping out hardware.
