The throtteling of the interrupt source leads to an exterme slowdown (e.g. 100 kB/s instead of 2.5MB/s on xl) of cardbus devices (3com 3CCFE575BT and Linksys WPC11 v2.0 tested). This error only appears if I enable acpi (apm is disabled then). Since suspend and hibernate do not seem to work with apm on the TP 600e in RELENG_5 (system freezes, but working on RELENG_5_2) it would be nice if the interrupt throtteling could be fixed.
