I don=E2=80=99t know if the kernel panics and unknown symbols are = related somehow, but they=E2=80=99re not helping(!) so I=E2=80=99ll try = to get past that. I don=E2=80=99t actually get logs in = /sys/kernel/debug/crashlog, so I can=E2=80=99t even prove it=E2=80=99s a = panic, but it=E2=80=99s rebooting that usually happens just as I do = something net related, like start typing in ssh or do an scp, after some = period of inactivity. If it=E2=80=99s reproducible on an unpatched build = I=E2=80=99ll head over to the OpenWRT universe.
