Can you please open a Bugzilla entry at bugzilla.kernel.org and attach the output of lspci -vvv, the contents of /proc/interrupts and a boot dmesg log from the affected machine to it? Ideally, both from a kernel that doesn't have the problem and from the affected one. Thanks, Rafael -- I speak only for myself. Rafael J.
