Hi, I can tell a little more. The total hang started after the update from April 9th. Downgrading systemd from version 24-1 (updated April 9th) to 23-1 'solved' the issue. May be this can give a clue? Martin Kho Btw. First tried to disable selinux, and downgrading kde related stuff without success.

Hi, Just after I uploaded the yum list my system froze ;-( I'll search somewhat further. You'll here from me later :-) Martin Kho
Hi, Arch... I feel a really big shame. Today I had a freeze on my production OS (Fedora 14). This made me think of I had a hardware problem. After re-installing my video card - I fiddled a little with an other card - everything is fine again. So sorry for the noise :-) For me this report can be closed. Martin Kho Btw. I had my printer and mouse on the same usb-controller. They are now on different controllers. Don't know if it matters. @Matej: Maybe it's useful to check hardware?
(In reply to comment #6) > For me this report can be closed. Thank you for letting us know. > @Matej: Maybe it's useful to check hardware? Well, if you come with some way how to do it without bothering reporters too much, I am all ears (go ahead and continue in this bug, I am still following it even when it is closed).
Hi Matej, With 'check hardware' I meant two things: 1. Physically inspect your hardware. I'm using a desktop pc so I can extend some components (eg. video card, HD, DVD) and clean connectors. In case you use a laptop this is much more delicate or maybe even impossible :-) 2. See if there are potential conflicts (interrupts eq.- this is from the old days, but you can never know). KDE has a very useful program for this - Kinfocenter. Under Device Information you'll find info about interrupts, USB Devices etc. In my case my printer and mouse were both sitting on the 8th host controller. Now I've put my printer on the 6th controller. You can also check if e.g the mouse is sitting on a usb port that is sharing it's interrupt with the graphics driver. Again, in the old days this was a problem, and maybe today it still can be :-) What I've learned from this report is that the EQ overflow can also be caused by a hardware failure. It's not always a software problem! As Adam Jackson put in [1]: ""EQ overflowing" is not a bug, dang it. It's a symptom." A symptom - in my case - of a hardware failure.

Yes, or it is quite caused by crash of something (so the events are not processed) or zillion other things. See bug 465884 for an example where everybody jumping on this message went completely out of hand and made the bug completely useless. Concerning your suggestions about hardware diagnostics. Either these issues are obvious and then I would expect minimal level of sanity on the part of reporter (checking that all cables are plugged in, etc. before filing the bug), or they are not obvious (like apparently in your case) and then we are moving into the dark areas of the hardware malfunction diagnostics, IRQ numbers and similar stuff, where most usual reporters cry in the horror. Remember, Linux is now supposed to work even for people who are more familiar with ICQ than IRQ. That's what I meant “bothering reporters too much”. Besides, hardware issues are not really not that much a problem to us. Usually either reporter comes with their tail between their legs (“Ehm … there was a disconnected cable …”) or there is something more serious (like in your case), and we hear from them. Or they simply evaporate and they are never to be seen again.
Hi Matej, I was thinking about the reason why this report went the way it went. All that talk about hardware etc. Now I saw the reason. Your comment (#2) on my report was just an excerpt from my Xorg.0.log file and I thought that you got the same error. Damn, what a sucker am I :-$. Sorry, again for the noise. And thanks for the discussion. ;-) Martin Kho

Sorry, again for the noise. yes, I am sorry, it happened to me couple of times … I should really add some line like "What a nice backtrace in your Xorg.0.log" or something.
