#80698 — Bug#1054345: linux-image-6.5.0-2-amd64: Segfault with USB Mass storage

Package: src:linux
Version: 6.5.6-1
Severity: normal

Dear Maintainer,

This is just a very preliminary report with little proper information as
yet: perhaps a placeholder which may be useful if other are seein this
problem.

Since installing 6.5.0-2, when hot plugging USB sticks, I see segfault
messages in dmesq such as:

------------------------------------------------------------------------------------

This has happened with at least two different usb sticks of very
different vintages.

I did run a memtest check on RAM, but this only seem to happen when
hotplugging USB sticks, so I am confident that this is a kernel/module
bug.

When I have more time, I will attempt to turn on debugging options and
symbols and more. But I doubt that I am the only one seeing this, and
maybe the bug is already fixed upstream.

However this was on hotplugging a garmin Etrex 20 which is always very
slow and after increasing /sys/module/usbcore/parameters/initial_descriptor_timeout
to a very large value (600000 !), so it may not be related.

Hi Marco,
  Were both these bugs supposed to go to procps? I'm not sure why the BTS
moved both.
I've tagged etc 1054345 so if you want one of them back, I'd rather you
took 1054346.
