Kernel version: 2.26.28.7 efs2progs version: 1.41.4 arch: x86_64 (amd) I made this test four times and the results were the same: linux freezes and becomes unresponsive. Only solution is to reset the box. I do not know if the problem is with the USB devices sub-subsystem or a possible ext4 race condition. That's the scenario: 1. a vg group (VGSTORE) using usb mass storage devices 2. a non-lvm controlled usb mass storage device named ANDREAS 3. a cpio operation running from the ANDREAS device to a VGSTORE.LV filesystem (LV1) 4. a cpio operation from a VGSTORE.LV filesystem (LV2) to LV1 5. a rm operation on LV1 Nothing is recorded in /var/log/messages I know that this is not too much information but I'm keen to repeat the tests and turn on any debug options necessary to track the problem. -- Berendsen -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
