I've recompiled pwc adding some extra logging and this is the output The first error is kernel: pwc: Failed to set LED on/off time; error -110 . <<<<<<<<<<<<<< this is the first error Does anybody know what -110 means? Moreover, these 2 lines DON'T happen on a x86 kernel: pwc: probe() called [046D 08B2], if 1 kernel: pwc: probe() called [046D 08B2], if 2 any idea?
