I've yet to organize a build.

Meanwhile some more investigations, "vmstat -i" for calm and storm:
-----
interrupt total rate
irq1: atkbd0 1025 2
irq9: acpi0 204 0
irq14: ata0 327 0
irq16: uhci0+ 246 0

Dmesg is here: ftp://ftp.wart.ru/pub/misc/tos.dmesg.boot.txt .
BTW, some more observations. While downloading a file the system
goto watchdog timeout rather quickly, but the system works. If I
try to upload files the system works much longer (for a couple of
minutes) but then freeses. No ctrl-alt-esc. Only cold restart works.
Thanks!
