Bumping this again with a related issue on these same boards...
I solved the original issue by removing the smc91x and gumstix_smc91x
modules, leaving the smc911x and gumstix_smc911x as the modules in use. Why
both sets of drivers were installed at once I have no idea, but it was the
smc91x drivers that were causing my soft lockup issues in the end.
However, the network connection is extremely poor on these devices at random
times. We've disabled the console so as to access all 3 serial ports for
our application, so SSH is our only means of access via the static IPs set
on the devices. The gumstix will randomly experience 50%-90% packet loss
when pinging it, thus causing SSH to fail to negotiate a connection as well,
and for all intents and purposes rendering that gumstix useless to use until
it decides to start working again.
I'm in the frustrating situation of handing a working gumstix to a
developer, and he comes back 5 minutes later telling me its not accessible
on the network. I plug it in, see massive packet loss, unable to connect
across multiple reboots...then it suddenly just starts working again like a
charm. No IP conflicts happening, happens with diff network cables and
jacks and computers, but entirely at random on any of them, and we really
need something thats not a 5 to 1 chance of failure any and every time its
powered on. The problem even exists just doing a straight crossover cable
connection to another PC.
So, again, are there any updated drivers out there that might address these
various issues? Anyone seen such network problems before?
Thanks,
