I already posted this to freebsd-questions, with no response, so far. As this is rather a problem closer to hardware issues, so maybe here I have a better luck. Hope nobody blames me for crossposting.

You are getting NMI's. Have you tried checking the system's event log (if it has one) for messages about hardware errors?
Thank you, John, for paying attention.
The mb is intel S5520HC so it has event log. From your article http://www.bsdcan.org/2008/schedule/attachments/45_article.pdf I found that I yet needed impitool, so I installed it.
`impitool sel elist`
shows quite a lot of messages already stored like these:
e05 | 06/24/2010 | 18:08:24 | Critical Interrupt PCIe Fat Sensor | e06 | 06/24/2010 | 18:09:28 | Critical Interrupt PCIe Fat Sensor | e07 | 06/25/2010 | 16:12:56 | Critical Interrupt PCIe Fat Sensor | e08 | 06/25/2010 | 17:34:16 | Critical Interrupt PCIe Fat Sensor | e09 | 06/25/2010 | 17:34:55 | Critical Interrupt PCIe Fat Sensor |
They seem to appear exactly at the moments of system lockups - the last two were appended after I made another try.
Intel document related to the motherboard
says something about these messages, but in the context completely unrelated to my case.
Hmmm. You might have a hardware issue. OTOH, you can try seeing if you have a BIOS option to disable PCIE error logging. If so, turning it off may fix your hangs since as the act of writing the entry to the system event log can take several hundred milliseconds on some machines causing a hang of sorts. If you still get hangs with the option turned off then it seems you have some sort of hardware issue, possibly in the mfi(4) adapter or mainboard.
