Bug Description
I don't know what caused it but ifconfig is hanging.
Here's dmesg output:

Same thing happened here with newest Dapper (Flight-6 default install) when trying to mount an XFS partition.
PC is down at the moment, so can't post more, but it was the default packages of the i386 CD on a AMD64 X2 Dual-Core system.
This behavior didn't change even after installing the SMP-k7 kernel packages.
Flight-5 AMD64 CD worked fine.
