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?

It's at http://www.zip.com.au/~akpm/linux/patches/stuff/oops.jpg

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
Bus 003 Device 003: ID 07cc:0301 Carry Computer Eng., Co., Ltd 6-in-1 Card Reader

I think that we have a patch in 2.6.17-rc2 that should let devices like
this work without crashing the kernel (note that your device is lying
about what it says it has.)

What kind of device is this?  Is it shipping so that people can buy it?

thanks,
