Thanks for the pointer. I have seen a number of screen freezes on my workstation, an Intel i7, 6GB ram, encrypted 2x 2TB SATA (6Gb speed) RAID1 (mdraid), ATI HD59xx with F16 x86_64. Maybe I read a lot of pdf's but I have seen the majority of the freezes occur during resizing the Evince window or changing the size. I was under the assumption that it was caused by the radeon driver because I noticed that the temp of my videocard went to nearly 80C during regular usage. What I saw was a total screen freeze including the mouse. The clock would also no longer change. And I got no responses to a ping or ssh from my laptop to the workstation. Can you please confirm that you have seen similar symptoms? Because I thought that it was caused by the radeon driver I installed the proprietary Catalyst 11.11 drivers from rpmfusion. Since then I have no longer seen a freeze. Regards, Patrick -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

Re: I/O Bound Procs Clobbering Responsiveness
Hi, I'm afraid the problem is not specific to Fedora ... I see something similar on my Gentoo box after upgrading kernel from 2.6.39 to 3.0.6 I haven't tried with USB but I can see whole system being pretty slow if there is high SATA load. And also I had to stop bitcoin computations on my GPU, as the GUI became totally unresponisve while running poclbm - this didn't happen with previous kernel, I could run the computations in the background while working with the GUI. /me is thinking about kernel downgrade ...

My HDD is encrypted which likely doesn't help perf but its not normally this bad. I've been seeing it for a while, I can't say exactly when it started but its possible or around when I upgraded from F-15 to F-16 beta.

I noticed the same thing yesterday while trying to create a live usb key using livecd-iso-to-disk, only it only seemed to be impacting certain GUIs. While creating the key, firefox was completely unresponsive. Gnome terminal seemed to work just fine. Accessing the GNOME dash (either by pressing the meta key or moving the mouse to the hot corner) was unresponsive, but I could press CTRL-ALT-down to get to the second virtual desktop. In my quick tests in the airport this morning, the issue appears to be related to USB I/O (at least on my machine), as I can't reproduce the problem copying data from one SATA disk to another (using a SATA disk in the CD-ROM bay). I'll try to do some more testing once I get back home. -- Jared Smith Fedora Project Leader -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
I/O Bound Procs Clobbering Responsiveness
This a subjective comment, but it seems that I/O bound procs such as disk copy are seriously impacting GUI response more than before. For example, switching windows can take 30 seconds or more. Indeed it appears the system has halted except that the clock seconds keep ticking away.
