fixup descriptions in pci-pc.c

fixup descriptions in pci-pc.c

[Oliver Feiler]

	Ok, this is just a cosmetic thing, but I see that in 2.5.3 the printk 
text in pci_fixup_via_northbridge_bug in pci-pc.c was changed

- printk("Trying to stomp on VIA Northbridge bug...\n");
+ printk("Disabling broken memory write queue.\n");

	Can't we change this to some meaningful output in 2.4.18 as well? It's 
still the old text with pre7.

Bye

Oliver

Good idea.  I frankly hate that message as its vague and stupid.  Heh.  I
actually wrote it... but I did it as a patch to an older message and I
didn't want to really change the poetic essence of the function I
modified.

Feel free to patch this yourself.  I am a bit afraid to bug alan and linus
and marcello with such a small change :)

[Patch] (was: Re: fixup descriptions in pci-pc.c)

Hello,

	This just changes the printk in the via_northbridge_bug fixup to some 
more meaningful output as it is already in 2.5.3. Please apply.

Even more meaningful:

	"Disabling VIA Northbridge broken memory write queue.\n"

Woo hoo!  The new message is much better!!

Also, speaking of the pci-pc.c fixup for via.. I hear for some people it
causes massive system instability.. :(  Although for me it was the
answer to my woes.  What to do about that?

printk("Disabling VIA memory write queue: [%02x] %02x->%02x\n", where, v, v & 0x1f);

This way we will see exactly where and what changed
