Bug#324595: linux-image-2.6.12-1-amd64-k8: GPF in kswapd on AMD64
Package: kernel
Version: 2.6.12-5
Severity: important
Hi,
I was installing a package with dpkg when the kernel had a GPF. dpkg
was then stuck and I had to reboot the system. This is with the
Debian provided linux-image:

Since such errors are often hardware related here is some info that
lead me to trust the reliability of this hardware:
- RAM DIMMs are high quality Corsair 3200XL DIMMs
- I ran memtest for several hours without any problem
- the system is cooled by 3 12cm fans
- the CPU is very cool according to lm-sensors:
CPU Temp: +34.0°C (high = +80°C, hyst = +75°C) sensor = thermistor
- this system had high uptimes with previous kernels and no crash ever happened:
