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) best regards the nekoboi Am 15.07.19 um 13:24 schrieb Enrico Weigelt, metux IT consult: > On 09.07.19 11:52, Kinky Nekoboi wrote: >> Tested it both with microcode and without microcode.
