Modules without a MODULE_LICENSE or with a MODULE_LICENSE that is not recognised by insmod as GPL compatible are assumed to be proprietary. [...] 5: 'M' if any processor has reported a Machine Check Exception, ' ' if no Machine Check Exceptions have occurred. so: - the "G" flag is perfectly OK! (P would be the "closed-source" drivers) - however, the "M"(CE) flag is worryingly. The question is, if p54 causes it, or not? As far as I know, when a MCE gets logged a short message should pop up in the kernel's log and next you'll need extra tools like mcelog to see what's going wrong. Regards, Chr
