I'm experiencing sudden shutdowns on my Linux systems.
- Using Ubuntu 12.04, my kernel version is 3.5.0-37-generic #58~precise1-Ubuntu.
- Running a Acer M5 581t(G) with 6 gigs ram laptop. I have been experiencing this for more then two weeks.
Its shuts off all a sudden with no warning. The temperatures are listed below at shut off. I have Windows 8 on the same machine and no problems running Windows, no shut off. Only once, and I had to update the BIOS firmware.
$sensors Physical id 0: +51.0°C Core 0: +52.0°C Core 1: +45.0°C
/proc/interrupts shows my Thermal event interrupts as follows:
TRM: 1277 1278 1276 1276 Thermal event interrupt
There is no indication in
syslog that a request to shutdown has been issued.
What could be the cause of this behavior?
I've attached links below to my
/proc/interrupts, system log, and kernlog. I had two unexplained shut downs at roughly 12:24 and 12:26. both back to back. The first one occured right after I opened the lid after it being closed. The other was during boot-up to recover from the first crash.
