Comment 178 for bug 370173

The report to https://bugs.launchpad.net/ubuntu/+bug/370173/comments/129, take it from me

I've started with my current kernel:
Linux version 2.6.28-13-generic (buildd@palmer) (gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) ) #44-Ubuntu SMP Tue Jun 2 07:57:31 UTC 2009

Before stress $ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +53.0°C (crit = +97.0°C)
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +57.0°C

Laptop shutdown after 8 min 30 sec under stress -cpu 16 --vm 2 --vm-bytes 128M
8 min 30 sec - that's the time I will use for all further tests

Next I switched back to Jaunty kernel:
Linux version 2.6.27-14-generic (buildd@vernadsky) (gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu12) ) #1 SMP Fri Jun 5 10:14:59 UTC 2009

Before stress $ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +53.0°C (crit = +97.0°C)
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +63.0°C

After 8 min 30 sec stress $ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +74.0°C (crit = +97.0°C)
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +85.0°C

While installing 2.6.30 upcoming kernel got the following errors:
* vboxdrv (2.1.4) Cannot install this module.
* vboxnetflt (2.1.4) Cannot install this module.

Nevertheless
Linux version 2.6.30-020630-generic (root@zinc) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #020630 SMP Wed Jun 10 09:45:40 UTC 2009

Before stress $ sensors

Adapter: Virtual device
temp1: +41.0°C (crit = +97.0°C)
k8temp-pci-00c3

Core0 Temp: +45.0°C

After 8 min 30 sec stress $ sensors
acpitz-virtual-0

Just like that: 2.6.30 seems promissing.
