| |
I had backreved this system to 2.2.18-21 but I can reproduce this Oops on both 2.2.18-21 and 2.2.18-23. I am providing the Oops information from kernel 2.2.18-21 since this is what was running on the system at the time the pppd dial in server crashed.
The server crashes after several dial clients who are routing both IPX and IP attach and disconnect several times, then you attempt to telnet or ssh into the box over the ethernet link. The oops is actually occurring when a telnet session is attempted after someone disconnects from a pppd session.
This Oops was created against the System.map file for a 2.2.18-21 build. This bug takes about two days to reproduce, and also requires that the local gateway system be misconfigured to point a non-existent network route to the target machine. It's very difficult to reproduce, but is very annoying.

ksymoops 0.7c on i686 2.2.18pre21. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.2.18pre21/ (default) -m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
No modules in ksyms, skipping objects Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file? unable to handle kernel paing request virtual address 90c16C24 Oops: 0002 CPU: 0 EIP: 0010:[<c0137596>] Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010206 eax: 90c16c20 ebx: c16c6145 ecx: 00000000 edx: c0226e2c esi: c0259200 edi: c16c614d ebp: c0259200 esp: c17f9ee8 ds: 18 es: 18 ss: 18 Call Trace: [<c01377fe>] [<c0137816>] [<c0144bbc>] [<c0131238>] [<c0131434>] [<c013151c>] [<c012f532>] [<c010a2fc>] Warning (Oops_read): Code line not seen, dumping what data is available
