Public bug reported:
Hi,
Since the 'natty' upgrade, my system randomly freeze.
Some symptoms :
- first, screen is totally frozen
- song mute after some seconds after that
- some apps seem to continue to run
- Can't switch to tty
This issue can happens average three times a day.
I am using Ubuntu Natty x86 version on a HP a6520.
I have no idea if it is a kernel issue or a Xorg issue or others..
I noticed this particular line in kernel logs at the time of each freezes :
[ 536.288809] hda-intel: IRQ timing workaround is activated for card #1.
Suggest a bigger bdl_pos_adj.
I join to this report many other logs.
Tell me if you need more logs.
Thanks for your help.
Regards,
Thomas PIERSON
