Here is the scenario : # #do not unload uhci-hcd # kexec --load --initrd=/boot/initrd-2.6.11-mm1.img '--command-line=root=/dev/hda6 init 1' /boot/vmlinuz-2.6.11-mm1 # reboot [ wait for the command prompt ] # /etc/init.d/syslog start # cat /proc/usb/devices & [ press sysrq-t ] One can see 2 processus in 'D' state : - khubd in wait_for_completion - cat in __down/__down_failed/.text.lock.usb/usb_device_read also; note the message before an after Sysrq-t : new low speed USB device using uhci_hcd and address 4 device not accepting address 4, error -110 FYI : # cat /proc/interrupts CPU0 0: 1535222 XT-PIC timer 1: 6982 XT-PIC i8042 2: 0 XT-PIC cascade 5: 1644 XT-PIC uhci_hcd:usb1, uhci_hcd:usb2, eth0, Ensoniq AudioPCI 7: 0 XT-PIC parport0 9: 0 XT-PIC acpi 10: 2 XT-PIC ohci1394 12: 21150 XT-PIC i8042 14: 11182 XT-PIC ide0 15: 36076 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
