I'm getting this crash, not on elf(kernel+exec)/smp/scsi but on a old Thinkpad with a pccard ed0, a elf(kernel+exec)/up/ide. Thought since the reference to modules that pcvt instead of sc0 might work - no such luck. I get the panic right after the pcic is probed and before the pccard is initialized. >From the instruction pointer, nm /kernel | sort gives module_init. > > I checked, all my LKMs are brand new.
