The init.d scripts for net.eth0 have been updated. This updated breaks my 3com 905 card (3c900). It pops up with the error that there was no carrier detected - but there blatantly is, as when I commented out the detection stuff it worked just fine! Thing is - this could be a kernel driver bug - but it appears to have a rather adverse effect on a popular type of network card. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I experienced this problem as well with my on-board VIA Rhine (not sure if this is what it is, but it's what I enabled in my kernel.), after upgrading baselayout I looked on the forums and someone mentioned that you can do: dhcpcd eth0 and that worked fine for me. A new release of baselayout is definetely in order.
