Default Bug#498489: linux-image-2.6.26-1-686: disconnecting USB cellphone while using it for PPP causes oops

Package: linux-image-2.6.26-1-686
Version: 2.6.26-4
Severity: normal

When using a 3G phone over USB for PPP connectivity, the kernel oopses if
the phone is accidentally unplugged (or, as in the attached log, its battery
runs out) before pppd has been terminated. After this happens, ppp does not
work (and new pppd processes become unkillable) until after the next reboot.

This oops trace results from a Nokia 6120 rebooting due to a low battery
while it's in use by an i386 laptop (in the oops trace you can see it
disconnecting from USB and then reconnecting), but I've seen the same symptoms
when the phone was unplugged rather than rebooting.

I've also seen the same symptoms when a Nokia 6233 was unplugged from an
amd64 with etch's 2.6.18 kernel.

The nearest I can find upstream is
http://bugzilla.kernel.org/show_bug.cgi?id=4407 which was apparently
fixed back in 2.6.13 - perhaps by 2.6.18 it had crept back in?

Sorry for the late followup, we have a large backlog and are currently
sorting things out for Squeeze.

Does this still occur with 2.6.32? If so, we should report it upstream.

I'll dig out my old 6233 and get back to you... there may be some delay while
I find it :-)

Have you been able to find it? If you no longer have the hardware, we
can just as well close the bug.
