Hello,
I have a Sony laptop SZ series and I get the message
ata_piix 0000:00:1f.2: invalid MAP value 0
even with 'quiet' in the boot command line. I think it's because of a
controller
with no disk attached, but I am a total newb, so I went to #kernelnewbies and
I was told to post this here. The code that prints the message is here
drivers/ata/ata_piix.c +973.
I'm using this kernel:
Linux vaio 2.6.22-gentoo-r8 #1 SMP PREEMPT Sun Sep 30 13:19:56 BRT 2007
i686 Genuine Intel(R) CPU T2400 @ 1.83GHz GenuineIntel GNU/Linux
Below are the outputs that may be relevant for tracing the problem.
If anything else is needed, I can provide, but please CC me, because I'm
not subscribed to the list.
