This error is occurring every second for me. I found a copy of smc91x.c here: http://www.gelato.unsw.edu.au/lxr/source/drivers/net/smc91x.c Notice that lines 128-131 say the default is 5 seconds, but have watchdog set to 1000. I found the copy in the svn on my machine under: ~/gumstix/gumstix-oe/tmp/work/gumstix-custom-connex-angstrom-linux-gnueabi/g umstix-kernel-2.6.21-r1/linux-2.6.21/drivers/net/smc91x.c ..and noticed that this timeout is set to 1000 too. I have changed the timeout to 5000 and ran bitbake (this is clearly incorrect) to no affect. Quick description on how/where to compile this file that bitbake will realize a change anyone? :) Cheers, Stafford. > Do these messages come about once every 5 seconds?
