BB: WRT45GSv2 consistently reboots under network load

Reported by: accwebs@… Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Barrier Breaker 14.07
Keywords: crash spontaneous reboot WRT54GS WRT54GSv2 Linksys network load Cc:



First off, thanks for an excellent open source router firmware project.

I have a bunch of Linksys WRT54GS routers with 8mb flash and 32mb RAM. My understanding is that they should still (hopefully) work with OpenWRT BB, provided they have the higher flash and RAM sizes (like mine do).

A few weeks back, I tried upgrading one of them (Linksys WRT54GSv2) to BB compiled from source (svn release id 43380). To be clear, I compiled from the BB branch, not trunk.

Anyways, flashing worked fine and the router came up as expected. Configuration also was perfectly smooth; however, a few hours later, I noticed that the router spontaneously rebooted.

Further investigation shows that the router spontaneously reboots under any kind of moderate-to-heavy network load. This does not appear to be a wifi issue, because connecting via Ethernet and retrying the same download still reliably caused the reboot. (I was on wifi originally.)

After digging around the filesystem, it looks like a "crashlog" file is being generated (and preserved during next boot) whenever the errant reboot happens. I'll attach it to this ticket. Testing showed that the crashlog file changed simultaneously with a spontaneous reboot, but please note that I don't really know enough about debugging OpenWRT to say whether the crashlog is showing the issue or if it's something benign that's just happening simultaneously.

Any advice on how to further troubleshoot the issue is welcome.

Sorry - just noticed the title should be "WRT54GSv2 consistently reboots under network load".

Can a moderator correct the title?

I experience the same issue on a WRT54GS v2.1 with OpenWRT 15.05.1.
