[Bug 290498] Re: linux-rt restricted to one CPU

[Stephen Parry]

Hi,
Here are my experiences of using Realtime Dutchman's 25th May build for about 36 hours:
Firstly, I am running with a different installation order from RTD:
1. Install 9.04 studio (all multimedia options) - reboot
2. Install all updates - reboot
3. Add workaround for clash involving snd-hda-intel driver and my system (see below) - reboot
4. Install headers
5. Install image - reboot.
6. Enable memlock 50% nice -99 via @ -> System -> Administration -> Ubuntu Studio Controls - Reboot

My acpi works infinitely better with kernel than it did without!

I have not dared enable wireless yet in any shape or form because the
iwl3945 driver seems yet again to be very broken. I will try this later.

So far, my system:
- Boots
- Reboots
- Shuts down
- ~0% idle CPU
- realtime Jack
- captures and plays back audio (jack, audacious, audacity, ZynAddSubFx)
- suspends, resumes and hibernates (caveat -  some processes exit)

* IT DOES THESE RELIABLY *

This is 100% improvement on the stock studio realtime kernel.

My snd-hda-intel needs a tweak to alsa-base.conf and the volume controls, but this is nothing to do with this realtime kernel; it's been a problem with my system at least as far back as hardy:
options snd-hda-intel model=dell-m27 enable_msi=0 probe_mask=1
Unmute the capture channel in the standard volume control / alsa mixer.
For those interested, without this JACKD watchdog timeouts trying to open the capture channel.

My system is as follows:
Dell Inspiron 9400 / E1705, 1GB memory, Core Duo 1.8GHz, Intel 945GM graphics, SigmaTel HDA, Intel 3945ABG wireless.
