Description Maik Ehinger 2005-07-22 23:46:09 UTC

Hi,

on my thinkpad t42 i recognized that after resume from suspend my GPU 
temperature raises rapidly ( 5-10 Min.) about 10 degrees centigrade over normal.
( 55 degress instead 45 degrees). If i restart my X server temperature goes down 
to 45 degrees in about 1 minute.

I'm runing xorg 6.8.2 on FreeBSD 6.0-BETA1.

If you need more info just ask.

Thanks in advance

maik

Are you suspending with APM or with ACPI?

Not a dupe of 2974.

Possible fix

Does this patch help? Beware that it's only compile-tested.

Comment 4 Maik Ehinger 2006-05-11 01:26:53 UTC

I tested it with Xorg 6.9.0 without success. 
Is your patch already in 6.9.0?

Thanks

Maik

Comment 5 Michel Dänzer 2006-05-11 02:19:41 UTC

It isn't applied anywhere yet, I developed it just before I attached it here. :)
It shouldn't be hard to merge it to a 6.9 tree though.

Comment 6 Maik Ehinger 2006-05-11 19:00:56 UTC

ok, i tested it with 6.9.0 and your patch applied.
I get the same behavior. I have to restart the X Server to see temperature drop 
to normal.

Comment 7 Michel Dänzer 2006-05-11 19:19:57 UTC

Bummer, thanks for testing though. Does the log file get a new line

(II) RADEON(0): Dynamic Clock Scaling Enabled

every time you suspend/resume or switch to console and back though?

Comment 8 Maik Ehinger 2006-05-11 19:34:28 UTC

Yes

Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
