Re: Kernel Ooops upon USB disconnect of a Western Digital My Passport 1TB drive
Just one more FYI, by blacklisting the ses module, the oops goes away.

blk_post_runtime_resume wouldn't be called unless the drive had gone
into runtime suspend. And even then, it's not likely to be called
after you unplug the USB cable.

I have enabled SCSI ATA Bus power management with this udev rule:
ACTION==add, SUBSYSTEM==scsi_host, KERNEL==host*,
ATTR{link_power_management_policy}=min_power
That won't have any effect on SCSI over USB, as far as I know.

Too bad; it would have been helpful. Is there anything I can do to make netconsole dump everything? Not as far as I know. But it might help if we saw the USB debugging messages. Try turning on dynamic debugging for usbcore and scsi_mod before running the test by doing: echo 'module usbcore =p' /sys/kernel/debug/dynamic_debug/control echo 'module scsi_mod =p' /sys/kernel/debug/dynamic_debug/control Had you made any changes to the runtime suspend settings? blk_post_runtime_resume wouldn't be called unless the drive had gone into runtime suspend. And even then, it's not likely to be called after you unplug the USB cable.

I'm uncomfortable having any plug-in utility writing to my disk after the crash since I'm using this laptop for work and have crucial data on it. If you have another computer handy, you can set up a network console (or a serial console) so that the entire oops message gets captured. Also, you could try running the latest 3.19-rc kernel to see if the problem has already been fixed.
