Yes, only faulty hardware or some code running with kernel mode privileges, such as a kernel module or built-in driver for some piece of hardware, can cause the crash. An easy way to test this is to backup to another storage device. Since he is, I believe, backing up to a USB connected hard drive, I suggest trying to back up to a SCSI or SATA connected hard drive. If that works, then there is a bug in the USB driver, a faulty USB port, or the USB drive itself is faulty. Code running with user mode privileges, like Bacula, cannot possibly cause the kernel to crash like this. If it can, then even that is a kernel bug. > Even if it is only bacula that is successfully pushing marginal hardware > over the edge, that is not bacula's fault. > > I have seen hardware that appears to work perfectly but cannot compile > software due to numerous unreproducible internal compiler errors.
