regression: msk0 watchdog timeout and interrupt storm

[Jeff Tipton]

Hi,

I also have this problem on Samsung N220 netbook, except I don't have 
any "interrupt storm" messages. When it boots up, it works a couple of 
minutes, and then "msk0: watchdog timeout" message appears. And, yes, 
the fastest way to reproduce the error is to try to copy a file via scp 
(even a 6MB file is enough).

I have FreeBSD 9.2-RELEASE on another partition, and msk0 works just 
fine there.

I also tried to change if_mskreg.h as Curtis suggested, recompiled the 
kernel but it didn't help; nothing changed :(
