Well, working sensors report temperatures in 34C (battery) to 68C range (PCI). guest@amd:~$ cat /proc/acpi/thermal_zone/THM*/* state: ok temperature: 58 C critical (S5): 127 C state: ok temperature: 67 C critical (S5): 97 C passive: 93 C: tc1=5 tc2=4 tsp=600 devices=CPU0 CPU1 guest@amd:~$ > Either that, or something in the driver is seriously broken. But > you're the first one to ever report that alarm :) Well, being only in kernel log, those messages are not exactly easy to notice.
