Description Frank-Michael Fischer 2006-03-10 19:14:35 UTC 
when in runlevel 3 (or 5) with a running network (wlan), "traditional" if-up setup, switching to runlevel 1 and back to 3 leaves the network dead. "dead" is the message coming from "rcnetwork status". Log tells me three times in a row: "request_firmware() failed for 'isl3890'" plus "islpci_reset: failure". Why would the runlevel switch from 1 to 3 even try reloading the firmware?

Workaround: Reboot and the firmware is loaded properly, the network card works.

Christian: Assign this back to us if this is nothing for you.

On my machines i get no trouble when switching runlevels -> no common problem --> not major.

When switching runlevels (even to 1) there is nothing that deactivates devices (by unloading modules, unbindig devices or invalidating firware). At least i'm not aware of something like this.

So what kind of device is that what asks you for firmware after runlevel switch?
Comment 3 Frank-Michael Fischer 2006-03-13 22:32:22 UTC 
It's a WLAN card based on prism54 chip. Works fine with ip-up setup otherwise. It's not supported through NetworkManager yet (bug 148210).

For testing I did install another (non-SUSE) linux (kernel 2.6.15) and did not have this problem.

If it's a normal or a major bug I don't really know. But if all firmware based network cards have got the same problem then it's a major bug, as most WLAN cards need firmware.

Switching to runlevel 1 kills all processes (also udev which is responsible for firmware loading). Switching back to runlevel 3 doesn't restart udev again which makes further firmware uploads impossible.

Christian, your ipw2200 still works after switching runlevels because it doesn't rerequest the firmware. So what do you suggest now upon my razor-sharp analysis of the problem? :)
Comment 5 Christian Zoz 2006-03-17 10:15:52 UTC 
See bug 158613, the udev problem is fixed already.
