Speaking of wakeup and EHCI: I'm trying to debug #9258. And only recently I saw
'irq 19 nobody cared' in dmesg output. But that only happened right after
resume from C3/C4 (don't remember exactly). I haven't seen that message in
other situations (eg. when the laptop runs normally). The laptop is a X61
Tablet with 2.6.24-rc3, without any bluetooth support compiled in. If you think
these two bugs could be related or want more infos about my setup just give me
shout.
