Hello,
I realize this is uClinux - but I received no response from the
uclinux-devel list so I am
posting here in the hope that someone will be kind enough to at least
give me a
direction in which to proceed in trying to track down this panic. It
only seems to
happen under heavy traffic - especially outbound, in other words
ethernet to modem to internet.
I am having trouble with cnxtserial.c causing a panic on an actiontec
dualpc
modem. I've looked at the code but can't figure out how I can be
getting a null pointer. I have very
limited experience working in the kernel so if anyone can give
somethings to try I would appreciate
it. Below is the output from ksymoops of the panic.
Could you please inform us about :
- the architecture (not obvious from the dump)
- the *exact* kernel version. uclinux and 2.4.32 are not enough. I
would guess 2.4.32-uc0, but I'm not sure that it's the only one.
Also, if you have other patches applied, please point to them.
- a list of the loaded modules and the .config
- how often it happens (every minutes, hours, days, weeks, ...) and
if you know an easy way to reproduce it (you only mentionned that
it *only* seems to happen in the circumstances above, but not if
it's guaranteed).
Of course, this will not guarantee that anybody will reply nor find
the bug, but right now, it might discourage many people from searching.
Thanks,
Steve

Thanks for the tip Willy,
The hardware is the ActionTec DualPC Modem it has a conexant cx82100
arm processor.
I can reproduce it at will by connecting to the internet and running
nttcp thru it at the same time
I am scping file both ways from and to, and then finally starting a
getty on /dev/ttyS0, the modem is
at ttyS1 and also ttyS0 is where all the kernel printk messages come out.
When I start the getty if I have all the other traffic going it
usually will panic in under a minute. IF I don't
have the getty running it will run for hours and not panic.
