Hi, me again, again a new problem with my laptop:

it's a old Vaio SRX41p, p3m at 800, no apic, the BIOS (Sony U2) assigns only irq9 
to all devices.
Enabling wpa_supplicant leads to interrupt storm messages.
I've been using this laptop with 6.2 heavily but never saw any interrupt storm 
message before.
Also tuning the sysctl vrom 100 to 500 hasn't helped (can't remember the MIB 
exactly right now, but of course will look if it helps).

I have compiled in cpufreq and I use powerd but that doesn't seem to be the 
problem because if the machine is under load, so that est doesn't step down, 
I also get the storm throttle.
