Bill,
I am using the True Mobile 1400 a/b/g, (bcm 4309 i believe) and can
make it panic. I am not exactly sure what is causing it, but if a large
amount of text comes over ssh (the only way that I have reproduced it
since adding saving dumps) such as untaring a large tar or 'du /' after
about 40-80 rows of output sent through ssh it panics. Not sure exactly
what to call it.
Here is a backtrace. If you need more information then this let me know.
Fatal trap 12: page fault while in kernel mode
