Re: FC6 T3 install woes


I tested the installation CD again and I think the problem (in my case)
is the sata_promise driver. See below.

After retesting, I realize this happens right after loading the
sata_promise kernel driver. I tested several times with and without the
SATA controller enabled in the BIOS, and the strange characters _always_
appear once the sata_promise is loaded.

Related to this problem, I've previously filed a bug (#199142) against
the kernel for FC5 (all 2.6.17 kernels have this problem for me). When
booting, I could see a "unable to handle kernel NULL pointer
dereference" message. Disabling the SATA controller makes this error
message disappear. I think there must be some bug in that driver that
causes the two problems.

The sata controller that I disabled on the BIOS is P20579. My
motherboard is microstar K8T Neo 2. For more info, the whole output of
lspci is on the bug report mentioned above.

I was wrong, I can confirm that the media check messages were actually
clear text:

During one of the tests, I had the problem with the black screen. When
the graphical installer is to start, the screen went black and couldn't
do anything, neither could I see the mouse pointer, nor could I go back
to the text consoles. I had to reset the computer. That could be the
memory corruption Paul mentions (BZ #206472), but I could not reproduce
it, it's strange that only happened once out of 10 tests I did (I would
expect it to be more deterministic).

Is there a bug report filled about the strange characters, by the way?

Hope it helps.
