Kernel News

Posted by vw72 in NewsJul 16th, 2009 | Comments Off

Just an update on the kernel situation. A new kernel is being tested that looks promising. If you’ve downloaded the latest kernel (2.6.30.1-kuki-20090707), you probably have noticed that the intel video driver is really, really slow, and you have to change the permissions on /dev/snd everytime you boot.

It seems that both of these issues have been resolved with 2.6.31-rc3. In testing, glxgears, using the default xorg.conf yields 826 fps (while glxgears is not a good benchmark, the 2.6.30.1 kernel only yields 140 fps). Also, the gstreamer permission error with the mixer also is fixed!

The downside — this kernel takes a couple of seconds longer to boot than the kuki kernel that shipped with Kuki 3.0 Pre Release 1.7.

Anyway, once this kernel passes testing, we will put it on the download page for general availability. We’ll post a notice here, so keep tuned!

New Kuki Kernel 2.6.30.1-kuki-20090707

Posted by vw72 in News, UpdatesJul 9th, 2009 | Comments Off

The latest Kuki Kernel is based on the latest stable kernel from kernel.org (2.6.30.1). For anybody who is interested, the changelog for 2.6.30.1 is located at here.

In addition to what was included in the 2.6.30-05-kuki, the 20090707 kernel has the following kernel settings enabled:
USB_EZUSB
USB_SERIAL_MOTOROLA
USB_SERIAL_QUALCOMM
USB_SERIAL_SIERRA_WIRELESS
SDIO_UART
UIO_PDRV
UIO_PDRV_GENERIC
AUTOFS4_FS
FUSE_FS
PCIEHP
ACERHDF

The kernel should now support ntfs filesystems and others that require FUSE.

Fan control now works (ACERHDF). To enable fan control open a terminal and type:
sudo modprobe acerhdf
sudo echo -n “enabled” > /sys/class/thermal/thermal_zone0/mode
(if the echo command fails, just edit /sys/class/thermal/thermal_zone0/mode and change the disabled to enabled)

Card readers should work if booting with a card installed. If not,
add “pciehp.pciehp_force=1″ (without the quotes) to
defoptions in /boot/grub/menu.lst
(success of the right card reader is tied to which internal revision of the aspire one you have)

The kernel is compiled with the “unsafe” options, so you should be able to suspend with a card in the card reader.

If you have an aao 150, and are having wifi problems, you may need to add “blacklist acer_wmi” (without the quotes) to /etc/modprobe.d/blacklist

Hopefully, with the addition of the above modules, most 3G modems/dongles/tethers should work (no guarantee as I don’t have 3G to test with).

If you have problems with this kernel, there is a special thread in the forum to post issues.

Installation instructions and the new kernel can be found on the Kuki download page.

New Kuki kernel available for download

Posted by vw72 in News, UpdatesJul 4th, 2009 | 9 Comments

We are pleased to announce that we have an updated kernel for Kuki available for download on our Downloads page. It is based on 2.6.30 and includes acerhdf for fan control, more complete ext4 support and some additional support for some 3G usb modems. There are also additional customizations for the hardware found in the Acer Aspire One, so you should see an improvement in speed utilization.

This kernel, does not have support for reiserfs, jfs or xfs, so if you use one of these file systems, you should not use this kernel.

Although this kernel appears to be very stable, and we don’t anticipate you having any problems with it, it should still be considered a “test” kernel.

Have fun and if you need help installing it, see the How To on the Downloads page.

Note: This kernel was compiled without the fuse module. If you need to mount an internal ntfs partion (or any others that rely on fuse), you will not be able to. The next kernel will have fuse re-enabled.
