I tried running GENERIC and i get the following lor and watchdog
timeout, no interrupt storms:

   Here is the full dmesg: http://cs.ubbcluj.ro/~dan/dmesg.txt.generic
   I tried also my kernel with apic, i don't get interrupt storms but
i get watchdog timeout message just like with GENERIC.
Here is the full dmesg: http://cs.ubbcluj.ro/~dan/dmesg.txt.apic
   And finally i tried my kernel without apic and without acpi, it's
running just fine, no interrupt storms, no watchdog timeout, but i
don't have acpi :(, here is the final
dmesg: http://cs.ubbcluj.ro/~dan/dmesg.txt.noacpi.
   Thanks,
