[Bug 614256] [NEW] display freezes on boot

Fri Aug 6 08:31:46 UTC 2010

Public bug reported:

About half of the time the display freezes on boot. It is just before
playing the welcome sound. It can also happen that it boots and then
there is a popping noise in speakers which does not stop.

My analysis of syslog shows in case of freeze:

Note that in second case we have this IRQ timing error with sound card.

It seems this problem is related to graphics card HD4550 which outputs
sound over HDMI. I am using open source drivers only.

In previous versions of ubuntu I had all kind of other problems with
this card.

In 10.04 I had no sound at all.
With Windows 7 on same machine everything works perfectly.

I know there are always hints on configuring the model in alsa-conf but
as my system is alpha-3 it would be good if somebody could tackle the
real problem.
