2.6.16.9, amd64, usbcore: NULL pointer dereference

[Harald Dunkel]

[-- Attachment #1: Type: text/plain, Size: 847 bytes --]

Hi folks,

Sometimes my PC dies at boot time:

:
usb 3-3: config 1 has 0 interfaces, different from the descriptor's value: 1
Unable to handle kernel NULL pointer dereference at 000000000000000d RIP:
<ffffffff8809493e>(:usbcore:usb_new_device+350)
:
:

Unfortunately it is not visible in any log file, so I took
a snapshot of the screen.

Surely it would be unacceptable to send huge attachments
to everybody on this list. Is somebody interested? Or is
there some upload area available, that I could use?

Please email the image to myself and I'll upload it.

Sounds similar to this?

Harald, if nothing happens on this bug (and it may well not :() could
you please remember to create a report against USB at bugzilla.kernel.org?

Thanks.

PS: I should mention that I had an USB disk attached at
boot time.

It should appear in the output of lsusb, too. If I insert
a SD card before booting, then I get:

# lsusb
