Hi,
After upgrading a Sony Vaio from SL4 to SL5, a strange (at least for me)
behaviour appeared for the network interfaces, eth0 and eth1. Normally,
eth0 should be assigned to the wired interface, and eth1 to the wireless
one. What happens now is that the 2 are swapped, i.e. eth0 is asigned to
the wireless interface...
Even more strange: this happens apparently randomly, i.e. I get
the right assignments about 1 time over 3.

Has anybody a explanation?
Not really, just some things to look at:
* Check whether you have a BIOS option that will "hide" a device when
not connected e.g. to a docking station.
* Check whether behaviour depends on booting with a connected network cable
* compare "lspci -vt" and "dmesg" output between two runs where the
interfaces jumped around, just to see whether for Linux the hardware
config has changed. Devices get detected one-by-one via a bus scan, this
should give the hardware ID (e.g PCI ID) which then determines which
driver to load. First driver to load gets eth0 etc. Some reshuffling
later happens for devices with explicit MAC address.
