Hi,

same problem here with FreeBSD 5.3-STABLE #3: Wed Feb  2 22:10:19 CET 
2005.

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.
