I don't see how the presence of DRBD would make the apic_timer_interrupt deref some bad pointer, while the cpu is "idle", with such "boring" backtrace, and for you only. But yes, I know, just having DRBD around makes it responsible for everything, I'm used to that. I mean, sure, in theory, it was possible, somehow... but I see no indication of that in the data provided. > More details below. [524641.634488] UDP: bad checksum.
