Description José Jorge 2011-05-07 11:28:48 CEST 
Description of problem:
- At boot time, system locks after showing #starting udev
- Even magickeys do not work
- Removing /lib/modules/*/kernel/drivers/video/via/viafb.ko.gz resolves the problem.

Could this module be blacklisted?

Comment 1 José Jorge 2011-05-10 22:15:18 CEST 
I have found that the file /etc/modprobe.d/blacklist-compat already blocks all fb modules except viafb one. This looks like it was forgotten.

Adding the line :

blacklist viafb

solves the bug. As this bug prevents using Mageïa LiveCD on VIA video hardware and a solution is known, I make it release blocker.

Hoping it can be done before RC1?

Hi there,
I hit the exact same symptoms but with a fresh install of mageia 1 on one of my computers :-(

The reason is not the same though, it comes from the modules firewire-core firewire-ohci that segfaults at boot on that device:

01:00.4 FireWire (IEEE 1394): ALi Corporation M5253 P1394 OHCI 1.1 Controller

I solved the pb by blacklisting them after having mounted my partition by other means. I guess I am a bit unlucky on that one, but that certainly needs to be reported in the install notes because is a no-go install for those having that card :-/

That precise card is known to have pb with the firewire module, but up to now, it was not imparing the kernel: see

Cheers,
Chris.

(In reply to comment #6)
That's a different issue (same symptoms, but different cause), please open a new report.
