Since upgrading to kernel 2.6.24 or 2.6.26 from the default etch kernel 2.6.18, I get Machine Check Exceptions. HARDWARE ERROR CPU 1: Machine Check Exception: 0 Bank 5: 1000001004000e0f TSC 0 This is not a software problem! Run through mcelog --ascii to decode and contact your hardware vendor Kernel panic - not syncing: Machine check With mcelog decoded error message: HARDWARE ERROR. This is *NOT* a software problem! Please contact your hardware vendor CPU 1 BANK 5 MCG status: MCi status: Invalid log BQ_DCU_READ_TYPE BQ_ERR_AERR2_TYPE BQ_ERR_AERR2_TYPE response parity error STATUS 1000001004000e0f MCGSTATUS 0 Any idea if this really is a hardware problem (bus, cpu, ram...?), or maybe caused by a faulty driver? Our hardware vendor told me that at least on windows this could be caused by a bad driver. TIA Ralf (Please CC me, because I'm not subscribed to the LKML, thanks!)
