Hello list I have trouble upgrading from latest snapshot to -stable :( The system will boot, but network won't start with ": no such interface" message. After loggin from console,when I type ifconfig, I'll get ": no such interface"
I thought I commented out some drivers, when building the kernel, but after booting freshly downloaded generic bsd, I'll get the same error. I have the old kernel -current (latest snapshot from ftp.openbsd.org few days ago, but lost the source tree unfortunatelly when updating) and it works when booting the old one. dmesg attached - there are both working and not-working one. Google didn't help. Does anybode have any clue? Thank you Peter Huncar
