-- Nothing in dmesg; when it freezes or reboots, even if there're some messages on console, they wouldn't be seen in graphics mode. As I said, now my suspicion is netfilter's ipt_recent; I've turned it off and now waiting. Another kernel I'm using now (2.6.24-ovz-006.5+) is built with stack usage reporting; that's the latest stack depth report:
[ 54.312696] modprobe used greatest stack depth: 3904 bytes left
Dunno whether it's rather low or ok.
-- End of message. Next message?
