Hi Misc,
Following Stuart's advice I've just upgraded my Libretto 70CT to the
latest snapshot but the kernel is still giving me the following error:
kernel: integer divide fault trap, code=0
Following is the dmesg and the output of ps and trace.
I'll submit a PR tomorrow if the combined genius of misc@ cannot
suggest an alternative approach to solving this issue.
Thanks
Fred

Libretto 70CT crash on cpu_switch
Hi Misc,
I was upgrading my Libretto 70CT from 4.3 to 4.4 and following a
successful install my libretto crashed at cpu_switch the same
happened with 4.4-current from the 30 Dec 08.
The output from ps and trace are shown:

This is the first time since 2.9 that my libretto has crashed on boot
- can anyone point me in the
right direction to help me fix this issue...
Thanks
Fred
