Unhappy regular lockups on hardy heron 8.04 LTS


for some reason ubuntu seems to lock oftern. pulseaudio seems to be the primary culprit in many cases which i can just kill, restart then hope pidgin doesn't go on a crazy ram eating rampage.

had a crash an hour ago in which pulseaudio died, then i killed it and restarted it but for some reason this didnt fix it (no errors) i began to get all the windows turn blank with only their title bars visable.
ctl+alt+bspace
login window came back but without sound still
repeated above key combination
GDM failed to load and loop-crashed.
I got a brief glimps in the terminal of some mass output from heci which looks to be some controller 'thing' on my board

I in the end had to reset for the sound, gdm to start working again.
does anyone have any ideas as to what on earth is going on here?
I realise it may not be the most informative post in the world but I need to get some stability on this machine before my term starts.

Ack! You're using vesa drivers? I know ATI drivers haven't been great, but there should be a driver that can do better than vesa.

pulseaudio is basically a proxy server, so while it might lock up your machine, it would be pretty unusual, if it's set up wrong it should just error out (or in my experience, it just does nothing, which is more frustrating to me). It's possible it might have an error that's chewing up memory, eventually locking up the system, though.

What are you doing when this happens? Perhaps it's youtube or similar videos, and when the vesa driver dies (wasn't really designed for such things), it leaves the audio in a loop that requires a cold boot? Perhaps all the modules needed for pulseaudio to use the soundsystem aren't installed? (I don't know which those might be, but it's possible it's trying to use something unavailable.)

Quote:
Host Embedded Controller Interface (HECI ) driver is a software interface that is used to communicate to the AMT subsystem (Management Engine) to access AMT capabilities. Communication between the local host operating system (OS) and the ME is accomplished by means of the HECI driver. HECI is bi-directional, as either the host OS or Intel AMT firmware can initiate transactions.
http://softwareblogs.intel.com/2007/...-heci-and-lms/

I don't know that HECI's your problem, it's likely just a symptom of your sound card dying and the OS looking for it. I could be wrong, though.

Not much help, but maybe it will help narrow your search. Perhaps there's a "plugin" for pulseaudio that's missing for your particular application/usage, too.

I dont belive i am using just vesa as it is using the intel driver which must mean that ubuntu config thought it'd be a good idea to call it vesa?

here is the exact error i appear to be getting which i think maybe related to my problem in some form
Code:
[ 1404.773700] heci: schedule work the heci_bh_handler failed error=0
Hmm thats interesting though, i began to get irritated with AMT because i updated the firmware and it would always come up with errors loading the amt engine so i disabled it. from here though it doesnt look disabled... maybe turning it back on in the bios then see if that helps this error...

hmm by soundcard dying do you mean soundcard failure or the related pulseaudio issue?

and yes for the record i do use youtube alot with flash 9, used to use 10 but 10 seemed very unstable

Did a google, similar cases might be due to KVM and a buggy kernel. From May this year:

https://bugs.launchpad.net/ubuntu/+s...vm/+bug/221032

By soundcard dying, I had an issue earlier this year that when I my system tried to suspend it wouldn't release the soundcard properly, and simply wouldn't return the soundcard to a usable state after I would shut the lid. I'd have to do a cold reboot to get the sound working again, though.

The rest was just me really too tired to be replying to posts...
