Re: C-States and Hyperthreading in Linux

Back from vacation! Yes, acpi_irq_balance is enabled by default when using IOAPIC so it shouldn't matter. Regarding acpi_osi=Linux you are correct. Specifying the OSI makes the ACPI code to take different paths, see code below: Method (_INI, 0, NotSerialized) { If (DTSE) { TRAP (0x47) } Store (0x07D...

Re: C-States and Hyperthreading in Linux

Thanks for the info, I'll give it a try when I get back from my vacation. Fit-PC2 and Fit-PC2i has different BIOSes, so this might not apply to Fit-PC2. Also, a good old stress test with tons of interrupts (preferably network and disc IO by transferring huge files) is needed to be on the safe side. ...

Re: "BUG: unable to handle kernel paging request" 2.6.31-34-fitp

Then my guess is that it's a software issue. If you still want hyper threading enabled there are some things you can try: * Do you have any usb devices attached? You seem to have some modules loaded that indicates this. Try disconnecting them and reboot. * When putting heavy load on the ethernet int...

Re: will there be support for ubuntu 10.04?

Just out of curiosity, has anyone tried loading the DRM modules in 10.04 and run X through the framebuffer driver? If so, do you get enough performance for it to be usable? The benefits over the VESA driver is that you can set proper modes and should get basic 2D acceleration.

Re: Power Button on Linux

The error message can probably be ignored. I get them as well but my power button works correctly. Check if you have /proc/acpi/button/power/PWRB. In Ubuntu you have /etc/acpi/events/powerbtn which maps the event to a script (/etc/acpi/powerbtn.sh in my case). This script decides what to do with the...

Re: ACPI Kernel issue

Hi Raidi, what you are describing sounds like a completely different problem. What you could do is check your RAM with memtest. Other than that I have no idea.

Re: Ubuntu 9.10 or something else

I'm not very updated on the IEGD driver but the original GMA 500 driver (PSB) had issues with hyper threading. I'd suggest you disable HT in BIOS and see if it solves any of your problems. The PSB driver is more or less an ugly hack and if IEGD is based on the same code it probably suffers from the ...

Re: Thermal zone driver available

Hi MikeMC, you can read the new sensors in /sys/class/thermal/thermal[2:3]/ and also in /sys/class/hwmon/hwmon[1:2]/

Output from my system:

Code: Select all

patrik@patrik-server:~$ cat /sys/class/thermal/thermal_zone2/temp

patrik@patrik-server:~$ cat /sys/class/thermal/thermal_zone3/temp

Have you tried any compiler optimizations? What arch and settings are you using?

Re: ACPI Kernel issue

Nobody seems to be working on it and I cannot do any further investigation without having a extra Fit-PC2 for debugging (will get one when I get my tax refund). I do think that blacklisting is good enough for the average user at this point. If it gets fixed later on the blacklist can be removed. Not...
