SubjectRe: PROBLEM: kswapd and toshiba libretto 50ct
it's not possible to change the laptop back to 75mhz... the process to
overclock it was to clip one of it's pins on the clock chip itself...

I have done many things on the laptop. I often compile things for GBA and
MSP430, i would've found any problem in those quite quickly. I have also
used povray on the CPU, also something that would show any problems with
the processor.

As for the database corruption; When talking with my brother, who's much
more knowledgable in linux, he pointed to a bug in the 2.2 kernels that
would corrupt or loose files when the system crashed.

I highly doubt the cpu would be at fault with this... there are no other
glitches past the problems with the database.

Now, one other problem that i have been having, and i thought it best to
go to a 2.4 kernel to try and fix it, is a second-long delay before
sending serial data... this has been seen with all programs i've tested on
the hardware, and is never around on other hardware.

thanks
Matthew
