Initially I could cause the locks to happen just simply by causing traffic on a device using the em driver (I would see abnormally high interrupts and than the system would hang). After that I switched to using polling on the device which stopped the system from crashing straight away, however eventually it does freeze. When the system hangs on about half the occasions I noticed even though it was non-responsive on the keyboard, I could get it to complain by hitting the power button and eventually something about the ACPI subsystem would come up (same message as PR 123729). The system is a Dell PowerEdge 2650. Its using a 64bit PCI RAID controller (one of the PERC LSI Logic ones -- which is also something in common with the other PR). >How-To-Repeat: Just simply boot the system and let it run for a period of time ;) >Fix: N/A >Release-Note: >Audit-Trail: >Unformatted:
