Hi There. With the debug on in hte kernel "ZABU" I found this when my Atheros card crash: lock order reversal 1st 0xc36c1e84 rl0 (network driver) @ pci/if_rl.c:1485 2nd 0xc0766280 bridge (bridge) @ net/bridge.c:777 Stack backtrace: lock order reversal 1st 0xc0768540 ifnet (ifnet) @ net/bridge.c:424 2nd 0xc379307c radix node head (radix node head) @ net/route.c:544 Stack backtrace: looks like is a Bridge problem, I have the option BRIDGE in my kernel may be I need try another way to make the bridge work? any idea. thanks Sam Leffler wrote: >On Tuesday 21 October 2003 06:49 pm, you wrote: > > >>I using a pentium III 350Mghz 256 MB RAM , uniprocessor, PCI Atheros >>Card Netgear WAG311 a/b/g atheros chipset AR5212, same thing with a >>DLINK PCI AR5212, the last update of my source was yesterday, anyway I >>have the same problem with older versions. >> I trying now with a diferent PC to see what happend. >>I hope this infromation help, pls tell me if you need more information >> >> > >Yes the information (especially dmesg) helps. > >Build your kernel with DDB, INVARIANTS, and WITNESS and -g.
