'jupiter': problem host
'neptune': my main workstation

I found that the screen had frozen on saturn, but the logged in terminal from jupiter was still active.

From jupiter, I had top displaying tasks from saturn.  I attempted to kill xorg which was at about 100% processor usage using the default signal, no affect.  Then I used signal 9, and got kernel messages on all my terminals logged into saturn (xorg cpu usage now about 0%).  Found the relevant section of the log and attached it.Linux saturn 

kernel: #1 SMP Tue Jun 16 23:09:06 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

I note that the first 6 lines, at least, of the call trace appear to be identical.

I think this is a duplicate of  Bug 488940
Comment 5 Jérôme Glisse 2009-10-14 06:50:41 EDT
Can you test with fedora 12 livecd and report if it works with it.
Comment 6 Nivag 2009-10-31 05:40:21 EDT
Sorry I can't, as the live CD fails to load properly see Bug 531945.
Comment 7 Vedran Miletić 2010-03-23 19:44:25 EDT
Can you retest now in F13 Alpha?
Comment 8 Nivag 2010-03-30 21:43:44 EDT
Sorry, it is not practical for me to run the Fedora 13 alpha, as the machine is both my main development machine and the gateway to the Internet for my local network.

I have been running Fedora 12 on saturn for a few months now.

However, I looked through my messages logs for the last few weeks and found no evidence of the 'radeon_read_ring_rptr' problem.

My current kernel is:
Linux saturn #1 SMP Tue Mar 23 09:47:08 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

I suddenly realized that I still had the SidePort disabled, as per:


Would it be useful if I tried restoring SidePort?
