В консоли и syslog каждые 5-7 секнд появляется это:

Uhhuh. NMI received for unknown reason 28 on CPU 0.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue

при этом пищит системный динамик. Я так понял поцессор шлёт куда-то какие-то прерывания, больше ничо не понял.

Там чёрным по белому написано:

NMI is non-maskable interrupt. It is usually caused by a memory parity error.

The obvious question is, has the memory been thoroughly tested or alternative known-good modules been tried. The linkage to devices tends to indicate RAM is fine but it would be good if we could authoritatively rule it out.

The alternative is that the devices are somehow messing with the system bus.

...

"One way to cause an intermittent NMI is by having power management enabled
with devices that don't support it. They see the world caving in when power
goes away and sometimes generate an NMI."

Ну так в гуголь!
