Hi,

Since 2.6.26-rc4 is out, I updated the bios and replaced one harddisk I=20
think its time for a status report ;)

Bios is now version 2.10 from 05/12/2008
 (http://www.asrock.com/mb/download.asp?Model=3DALiveNF5-eSATA2%2b&s=3DAM2)

=2DAHCI+nomsi: boots fine. Works fine. But: I still can not enable ncq
=2DAHCI+msi: the usual. No harddisks found, waiting for the timeouts, then=
=20
kernel panic because of missing root.

=2DNON-RAID/IDE+msi: works fine. No delays. No NCQ (not surprising since mo=
bos=20
handbook says that AHCI mode is required).
=2DNON-RAID/IDE+nomsi: see above.

Attached are kernel config used, lspci outputs and dmesgs. lspci was done=20
straight after boot without the nvidia-module loaded. Kernel is patched wit=
h=20
reiser4.=20

One thing that confuses me is this:
echo 31 > /sys/block/sda/device/queue_depth
echo: write error: invalid argument

but:

shouldn't controller and harddisks support turning on NCQ? The handbooks sa=

that NCQ is supported in AHCI mode and the harddisks doesn't seem to be=20
blacklisted.
