[SOLVED] New kernel needed

PostPosted: Mar 3rd, '13, 15:41

I have a strange problem with my Toshiba NB205-N2xx netbooks (xx = 10 & 35)

When booting, and sometimes when console-based programs are running, all I/O stops at various times until either the mouse is moved or a key pressed. That includes console output. Nobody else seems to have heard of the problem, but I have it on 2 quite similar Intel Atom based computers.

I have been using Gentoo on the NB205-N210 with no problems, so I know a solution is possible. I just do not know what the details are. I strongly suspect it is the way interrupts are handled.

Does Mageia tweak its kernels? I don't need the latest, since the computer is 4 years old. I just need the kernel source and Mageia's .config so I can try to nail down the problem. Where can I find it?

Thanks
Boba

Try adding clocksource=jiffies to kernel boot options, does that help?

Problem solved!
What does jiffies do? I looked up clocksource but the reference I got did not show 'jiffies'.

Bobalong, please mark the topic accordingly.

You can do so by editing the first message in this topic, and put [SOLVED] in front of the title.

Thanks in advance!!! :)

Done.

The immediate problem is solved, but I'd still like to know where to get the sources for Mageia's desktop kernel, including any patches.

Ok, first things first - i know that because my laptop showed that on some kernel update some time ago.
https://bugzilla.kernel.org/show_bug.cgi?id=11727
https://qa.mandriva.com/show_bug.cgi?id=44342
That is due to an ACPI bug, and changes the timer source.

For the Mageia kernel and it's patches, have a look at our SVN: http://svnweb.mageia.org/packages/cauld ... l/current/
And for a checkout including sources https://wiki.mageia.org/en/Mgarepo#I_do ... ng_mgarepo

Or if you just want to build a new kernel with minor changes, from the command line, as root,
Code: Select all
urpmi kernel-source-latest

This will install the kernel sources in /usr/src. You'll find the config file for the kernel you are currently running (and any others you have installed) in /boot, e.g.
Code: Select all
# ls -1 /boot/config-*
/boot/config-3.3.8-desktop-2.mga2
/boot/config-3.4.34-desktop-1.mga2
