Hi,
The cpufreq driver I wrote for the 750gx causes a kernel panic in 2.6.36.
This is from a screen shot:
[c6035f30] [c001014c] timer_interrupt+0x13c/0x19c
[c6035f40] [c0013294] ret_from_except+0x0/0x14
--- Exception: 901 at 0x1000c694
LR = 0x1000f3e4
Instruction dump:
4b48 38610008 4be7

You don't have a serial port ?
