After successful write on USB DVD-R writer (HP-200j), system oops's when unpluging USB device.
Same thing with 2.6.9-rc2mm1.
Try applying this patch:
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109744234829347&q=raw
Patch applied.
I have done the tests at still no good.
I connected and disconnected the writer a couple of times. WHen I didn't
read/write on the CD there is no OOPS when disconnecting. But after reading CD
there was OOPS when disconnecting. See below. Decoded OOPS - see more below.
Can you turn on the usb-storage verbose debugging option in the kernel
configuration and then try running your test over again? Be sure also to
set up /etc/syslog.conf to capture debug-level kernel messages.
Well, I think I must admit I was wrong.
I have done some tests and there was no ooops after succesful writing or after
unmounting device. The oops is when I unplug USB-DVD-Recorder when there is
already mounted device on it.
Then there is state transition from NULL->cancel and kernel oops! See oops and decoded oops below:
The null state and and oops are becuase of this http://marc.theaimsgroup.com/?l=linux-scsi&m=109733573729283&w=2
Oh yeah. that patch is not correct, but if you correctly modify it to use device_for_each_child per Christoph's suggestion, I seem to be getting some refcounting errors. For some reason the sdev will be released, but the sd.c still thinks it is there.
