Description Robin Knapp 2010-04-12 08:47:29 UTC

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

I've tested Live CD/USB Build 553 (M5) on a notebook with a Radeon X600 Mobility.
The radeon module does not get loaded automatically during boot (see Bug 595653), but if I boot into runlevel 3 and modprobe radeon manually, KMS gets activated (switches automatically to native LCD resolution).

If I start X after loading the module, the screen first gets corrupted (looks like some random memory content), and a few seconds later I see the KDE splash screen.
So in general this works, but it is painfully slow and the GPU fan turns up.

After a while, GPU reset messages are shown on the console:

[  124.160085] [drm:radeon_fence_wait] *ERROR* fence(f6a14e60:0x00000005) 508ms timeout going to reset GPU

See attachment 353616 [details] of bug 574749 for full dmesg output

Reproducible: Always

Steps to Reproduce:
1. boot live cd/usb into runlevel 3 on notebook with X600 Mobility
2. modprobe radeon
3. init 5

Could it be a problem with fb vga mode which is set when booting the live cd?
Will test a real installation later this week...

Need to check that.

Comment 4 Stefan Dirsch 2010-04-12 15:34:52 UTC

I don't see that issue with my M24 card.

Comment 5 Stefan Dirsch 2010-04-12 15:56:33 UTC

Meanwhile I *do* see this issue with my M24 card with KMS enabled.

Comment 6 Stefan Dirsch 2010-04-12 15:58:10 UTC

Finally close as duplicate.
