Some chips need AHCI_EN set more than once to actually set it.  Try a
few times before giving up and spitting out WARN_ON().

Have you backed out the original patch?  It works fine here.

I removed the whole directory and installed the sources (with emerge 
vanilla-sources).
 After the failed attempt  I removed it again and unpacked the tarball - same 
result.

I copied the text from kmail into nano and kedit - and both produced identical 
patch files. If it is some whitespace damage, it should still apply, correct?

Glück Auf,
Volker

Ah.. right.  The patch is for libata-dev#upstream branch which contains 
ahci_enable_ahci() refactoring change.  You'll need to get the latest 
linux-2.6 git tree which contains it.

which isn't -git4

*sigh*

then I did:

If you can git, just do the following...

$ git fetch git://git.kernel.org//pub/scm/linux/kernel/git/jgarzik/libata-dev.git upstream:upstream
$ git checkout -f upstream
$ patch -p1 < ahci.patch

Thanks.

Heh... it should have been git://git.kernel.org/pub/scm... w/o the

emm, even without the double slashes I get the same message:
git fetch git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git

git fetch git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git

all three 'working' setups booted without any delay (but it were only reboots, 
no cold boots).

complete dmesgs are attached.

Btw, when I edit the grub boot prompt, crap was/is attached. That crap shows 
up in the non-raid+msi dmesg. And it made the kernel panic on reboot. Apart 
from that it doesn't seem to have any influence. 

Reiser4 was not patched in.

Glück Auf,
Volker
