| |
This new crash is different from the previous that I reported, in that no network activity is related. It happend while installing Staroffice. It appears to be quite reproductible in my machine.
To get a log, I started Staroffice instalation with ./setup /net. Then I switched to a text console so that the kernel message could be seen. After some seconds the machine was hang, including no ping. The message was copied by hand, as well as symbol translation. Please forgive any mistakes. Address are hexadecimal, but offsets are decimal.
Kernel version is 2.2.13pre13 from Alan. I tried it following advise Wade Hampton. I the same crash with 2.2.12. I can give you the logs if you wish.
For those that did not read my previous message, this a SMP machine, two processors (Pentium II).
Here is the log:

Opcodes from kernel log appear to match with those from objdump.
Source code from GDB (source file kernel/sched.c, line number in the first column):
