Christian, thank you! I recompiled my kernel without ACPI/APM, with debug option. I've updated BIOS. I'm testing the system now. About any results I will tell later. ... but I don't understand why machine should go to suspend or hibernation through high user/system activity... o_O Christian Walther wrote: > This is just a wild, uneducated guess, because I'm not a long FreeBSD > user, but from my point of view this error could really be related to > ACPI/APM, as already has been suggested. > Maybe the machine is trying to go to suspend, but fails while doing > so, which in the end would mean that it can't recover from the > suspend, but has to reboot completely, resulting in dirty file > systems.
