Hi,
The mail from Holger Glaess seems to be missing a backtrace. I got
one, but
I have very little time today and tomorrow to debug anything, I have
put a
temporary replacement for the octeon pppoe router at my premises for
the time
being.
Also, I tried poking around in sppp_auth_send() in
/sys/net/if_spppsubr.c but
to no avail. The fault lies in bcopy() in that function. In the
backtrace
it shows up as smallcpy(). When pppoe0 is disabled the kernel
doesn't panic.
My bt follows with dmesg from my machine that was upgraded to 6.6.
After that Holger Glaess's mail which I had to fish out of my trash as I
had accidentally deleted it.
