Package: linux-image-2.6-amd64
Version: 2.6.29-5
Severity: normal
Tags: upstream
The garmin_gps module stopped working for connecting to Garmin 60Cx device
with gpsbabel. Since rebooting to kernel 2.6.25 makes it work without any
other changes to the system, I conclude it's driver problem rather than
gpsbabel problem.
The symptoms are, that when I run gpsbabel, either upload or download, with
2.6.29 or newer kernel, it locks up (stays in D state) and is not killable.
The Garmin MapSource running in Wine seemed not affected though, at least for
upload.
First known-bad version 2.6.29
Last known-good version 2.6.25
Note, that I already have newer kernel -- 2.6.30+20 -- installed (and the
dmesg output below is from that version). I am reporting against previous
version because I first noticed the problem there. Below you will find
relevant content of dmesg.
I am quickly posting this now in the hope that the trace below gives some
hint to somebody. Otherwise I will try bisecting it, but it will take me some
time to learn sane process for installing the non-Debian kernels here.

The message repeats every 120 seconds and looks exactly the same (except for
the timestamp, so I won't repeat it here).
Last, I have tried SysRq+w and here is what appeared in dmesg after that:
