The issue still happened even using the kernel compiled without any watchdog support. The netconsole log didn't include any details. It just rebooted again without any indication why. That was about 24 hours after the last restart. I still had the watchdog package installed (but with even the software watchdog disabled in the kernel, I didn't think it would do anything). Well, I now removed that, but I'm not convinced that it did cause the reboot.
