Hello Glauber,
I have rebooted the server with 2.6.27.1 + this patchlet an hour ago. No problems since.
Hardware: Compaq P4 Xeon server, Broadcom CMIC-WS / CIOB-X2 board. Tell me if you need more detailed information.

Hello Ian,
it seems we're hunting down different bugs after all. Too bad, I hoped I could have solved your problem, too. Our machine has been running well over the weekend with the patch I posted; with faulty kernels, the problem would occur after a few minutes.
