Hello *, a couple of weeks ago, i posted a "success" message. This time i have a strange issue to report. A couple of weeks, with only one Samsung HD401LJ and everything was fine. Yesterday, i put another drive a Samsung HD501LJ into the second bay and shortly after this. (After FDISK and MKFS and a couple of powercycles) The device is completely unresponsive. With this device on, Windows XP freezes instantly...Linux shows the following at turning on: And everytime, when i played with this device, he said something about USB...WTF?! Same IRQ? I dont think so: <interrupts> cat /proc/interrupts CPU0 0: 876859 XT-PIC timer 1: 7955 XT-PIC i8042 2: 0 XT-PIC cascade 5: 466863 XT-PIC libata, libata, libata, eth1 7: 347524 XT-PIC libata, eth0 9: 0 XT-PIC acpi 10: 931 XT-PIC ehci_hcd:usb1, HDA Intel 11: 211376 XT-PIC ohci1394, nvidia 12: 25578 XT-PIC i8042 14: 46 XT-PIC ide0 NMI: 0 LOC: 876799 ERR: 1 MIS: 0 </interrupts> beneath you find some logs: 1. first time i put the device on with the new harddisk added 2. "test" of hotplug 3. device is dead any clues/hints what i could do?
