with a random config kernel i'm getting this during bootup: [ 23.061449] cops.c:v0.04 6/7/98 Jay Schulist [ 23.067416] lt0: cops at 0x240, IRQ 5, in Tangent mode [ 23.106029] lt0: Bad packet length of 65535 bytes.

Config and bootlog attached. I guess the core problem is that somehow the the cops driver got registered to IRQ5: [ 23.067416] lt0: cops at 0x240, IRQ 5, in Tangent mode is this an old ISA driver perhaps that should i exclude from this randconfig testing?
