Description

I am running 12.09 final on WRT54GS v1 unit. Sporadic panic/reboot noted. I substituted an indentical WRT54GSv1 and power supply to eliminate hardware issue. Problem persists. Both units are fairly clean, I run no additional packages and WiFi is disabled. I have serial console attached and have been capturing errors. I will attach the minicom.cap file to this ticket with the console log for completeness. The interesting part is:

Please build an image with "Compile the kernel with symbol table information" enabled and post a stack trace with kernel symbols.

God it's been years since I built an OpenWRT image. Should I download trunk, or stick with the 12.09 final? I tried bleeding edge r38843 and it's also crashing.

comment:5 Changed 4 years ago by hauke

Please post the error message you get in trunk, the one you posted here does not have symbols in the call trace that make it unreadable.
