2.6.18.1 hangs after resuming from apm suspend

After upgrading from 2.6.16.20 to 2.6.18.1 my Siemens Scenic Mobile 750AGP Notebook hangs after resuming from suspend.

However resuming from suspend works properly if:

- the prism 2.5 WLAN card is removed before suspending
- the prism 2.5 WLAN is removed after resuming

Here's the content of /proc/interrupts:

This is what happens after initiating apm -s;

This probably is a regression in the prism driver.

Well, it looks like you need to file a bug report at bugzilla.kernel.org.
