    Subjectusb fails to suspend [was: mmotm 2009-06-05-16-19]
    Hi,

    there is a suspend regression somewhere between mmotm 2009-05-17-12-15
    and 2009-06-05-16-19:
    hcd_pci_suspend_noirq(): pci_prepare_to_sleep+0x0/0x80 returns -19
    pci_pm_suspend_noirq(): hcd_pci_suspend_noirq+0x0/0xb0 returns -19
    pm_noirq_op(): pci_pm_suspend_noirq+0x0/0x180 returns -19
    PM: Device 0000:00:1d.2 failed to suspend late: error -19

    $ lspci -xxvvs 0000:00:1d.2
