[sda] write cache: enabled, read cache:enabled: doesn't support DPO or FUA, sda:

[Zeno Davatz]

Dear List

After my latest git pull from

url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

I done

make silentoldconfig
make modules_install

copied the bzImage to /boot and ran lilo.

When I want to boot into 2.6.28-rc2 I get:

[sda] write cache: enabled, read cache:enabled: doesn't support DPO or FUA, sda:

Also see my screenshot:

Thank you for your Feedback.

Zeno

How recent is that pull? This looks like something fixed in-between -rc1
and -rc2. So I'd double check that you are after or on -rc2 and that you
are booting the right kernel.

That Pull is from right after Linus released 2.6.28-rc2. I always pull
after Linus releases an rc and notifys everyone through the list.

I will pull again right now and try again.

Please do, and if it still breaks then use netconsole or a serial
console to capture all boot messages!

Ok, this worked, thanks! I am now on 2.6.28-rc2-00095-g49fdf67.

The only thing remaining is that my time is now

04:17

instead of

16:17

Any hints on that?
