Hi all,
I tried a Ubuntu 13.10 image from http://www.armhf.com/index.php/download/ . System boots OK. But after I apt-get installed a ubuntu-desktop and try it on HDMI, a kernel BUG pops out:

Well, try disabling, as it was the only recent change...
https://github.com/RobertCNelson/linux-dev/blob/am33x-v3.8/patch.sh#L738
BTW, the ubuntu desktop seems very buggy, I even cannot login to my
desktop... ;(
Honestly, "ubuntu desktop" unless you have a dual core arm with 1GB
don't even bother as it's a complete waste..
Regards,
Nop, I reverted "Make the McASP code generic again, remove all hardcoding"
on the git tree but it still have the same BUG. Here is my whole config:
Laughs, so you wanna 'retry' with the shipped config, instead of a
totally custom config...
Regards,
But the shipped config does not have CONFIG_DEBUG_ATOMIC_SLEEP enabled,
right? So it definitely won't yield that BUG.
I will try the shipped config with CONFIG_DEBUG_ATOMIC_SLEEP enabled.
Or just switch to 3.12.x branch as it's just better across the board
usb wise (minus the lack of full cape support..)
Regards,
Thanks, I will give 3.12.x a try when I have time. Which version of kernel
is stable enough and recommended for production usage? I mean, ship to
industrial customers.
Laughs, well obviously the one you want to personally 'support' those
customers with...
The shipped config(
https://github.com/beagleboard/kernel/blob/3.8/configs/beaglebone ) is even
worse:(both with/without "Make the McASP code generic again, remove all
hardcoding")
