Public bug reported:
These kernel warning started to happen pretty consistently after every
reboot somewhere during the lucid alpha cycle and have not stopped
since. I just realized that there might be a connection to a regression
with gobi_loader (the firmware loader for the internal gobi WWAN chipset
of this notebook): https://bugzilla.kernel.org/show_bug.cgi?id=15134
While the WWAN module worked in Karmic without problems, it fails in
Lucid.
Now, the kernel problem reported here could be the cause or could be the
effect of this.
