Hello,

I am triying to write a tty_driver under ppc. And I get a kernel panic.
Can somebody explain me how finding the source of the error with a kernel
panic trace :
thanks

hi

i ran in some trouble with the TRACE-target.
i'm using
kernel: 2.6.14.7
iptables: 1.3.5
and the patch-o-magic from 12 march

the patch doesn't apply (depends on raw), although the raw table exists already.
iptables seems to know the TRACE target, but i found no kernel modul.
forcing patch-o-magic doesn't help (ipt_TRACE.c exists now in the
kernel tree, but the module isn't able to compile, i deleted the
"depends" entry...).

i have some troubles with mark, connection tracking and i think it
would be useful to use TRACE for troubleshooting.

is there an known issue about the TRACE target? or does anyone have a
working setup (kernel version, iptables version,
patch-o-magic-version)?

iptables prints this error:
sudo /usr/local/sbin/iptables -t raw -A PREROUTING -j TRACE
iptables: Unknown error 4294967295

regards
moritz
