Hi,
After a previous post about a Dell 5000e Inspiron crashing when Speedstep kicks in I have set up a serial console, and this time, when copying a file between partitions, in plain old console, no X, network not configured, etc etc, plugging in the power (while the system was running on battery - this causes the CPU to step up to 700MHz from 550MHz) causes the system to freeze in every way (including SysRq), while continuously spitting out "Unexpected IRQ trap at vector 20" on the serial console.
I realize that probably more information is needed for this to be useful (if it is not just a 'shitty hardware' thing) but I am not sure what would be needed, so if you need to know anything, just drop me a line.
Kind regards, Dennis Noordsij
