OK, time to ressurect the topic ;)
There is another report (from Anisse - CCed) - MSI AE2220 stops for 10
seconds when we try to see if "AUX DISABLE" command took effect (it
doesn't). While we should reduce the time we wait and retry to something
more reasonable it woudl not fix this issue completely.
The box does not have any PS/2 ports but in this case BIOS writers _did_
some crack and put PS/2 devices in DSDT. While the devices are most
likely not active and thus Matthew's patch would help Anisse I do hate
to loose the option of plugging PS/2 mouse/keyboard after boot and
having chance of them working. I would still like to add a few blacklist
