[ltp] T22 and ACPI suspend

[Silvio Böhler]

Kernel 2.6.11 with ibm_acpi 0.10 patch

Hello

I can successfully put my T22 to sleep using

echo -n 3 > /proc/acpi/sleep

and wake up again using the FN key. The problem is that after wake-up, 
my USB port somehow stops working due to an interrupt issue (see the 
bottom of this message for the relevant part of my syslog). Does anybody 
have an idea how I can solve this?

Thank you!

Silvio
