| |
Here is two opses that I found in the logs on two separate machines running kernel 2.0.32. These machines mostly run pppd. The opses did not freeze the machines, but they were probably swapping due to the kernel memory leak I've reported many times now. I can't find any way of reproducing these opses.
Unfortunatley I've had several complete system freeze + black screen + nothing in the logs. I did not experienced any of this with kernel 2.0.29. My average uptime is less than 3 days now. :( Not Good compared to 2-3 months using 2.0.29.

Using `/boot/System.map-2.0.32' to map addresses to symbols.

And the other one looks very similar (sorry, klogd had already mudged the addresses so ksymoops did not like them):
