Yeah, that's the new polling code kicking in. If the IRQ problem
doesn't persiste (which should be the case here), polling will step
down after a while and everything will return to normal. If you keep
the system running more than ten minutes and use the CF device, does
the kernel complain anymore?
Thanks.
