That is a good hint,
i have build several kernels ... but all newer ones arent booting..
i guess i will build another one with CONFIG_DEBUG_SPINLOCK enabled.
I am on vacation right now and have no physical access to the affected machine right now. Will try it next week.
I would like to know if any one here has an KGPE-D16 running with an newer linux kernel ( I always thougt this would be the mainboard of 1st choice for coreboot and it would be much more used)

Did you also test it w/ recent mainline kernel ? (w/ CONFIG_DEBUG_SPINLOCK enabled)
(personally, I've long given up walking through Debian's kernel mess, just use upstream 'make deb-pkg' directly)
This particular bug smells like a kernel bug to be:
