Description of problem: The operating system environment is unstable. Am experiencing system freeze-ups at random times. Two issues seem to be a problem. First is sound-related, and the second is scanner-related. In one instance various programs were open, including listening to an Internet stream on QMMP. Started a youtube video in browser and the system ground to a halt and froze. Even the mouse was unresponsive. Perhaps the system cannot handle multiple streams as it should. Another example was when the system was trying to use the scanner. I started Simple Scan while just Firefox and Thunderbird were open, and the system froze with the scan program full screen but with active mouse action. However, the mouse could do nothing and there was no way to stop a program. The system was frozen in that state. Evidently, the system slowly builds to an overload state and freezes. Unfortunately, there is no way to notice until it is too late to respond. Upon resetting from this last example, the action following the grub menu was strange. A few lines of error messages appeared and the word "froze" displayed in one of them. Then a blue, multi-stage progress bar appeared across the bottom of a blank screen with the number 18 at the right end. At some point in its progess, it jumped to the center of the screen and changed resolution. It finally showed a small command-line-like line of boot up detail, and then immediately gave the normal login action. All very bizarre and unhelpful actions. ABRT does not capture these events. Obviously there can be no screen shots. Version-Release number of selected component (if applicable): Fedora 18 with Xfce 4.10.0 How reproducible: Unknown Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Smooth integration of all processes. Additional info:
Are you still seeing this with kernel 3.9.8 or newer? If so, can you attach the output of dmesg?
Just fedup-d my system to 19 and did try the simple scan program again. This time there was an improvement. The program opened and, upon selecting to scan, it reported that no scanner was available and did not freeze up at all. I was able to close the program and everything is good. I have not tried the multiple sound programs again, but will report here if I see any more system freezes of any sort. I will say that fedup stopped after reboot with very little progress indicated on the progress bar. It had been left running for a couple hours. But I reset the computer and it came back up as the first item on the grub menu, so I selected it and let it finish. This time it completed after a fairly short interval; probably less than 30 minutes. However, after it rebooted it came up to an unknown screen, because when I came back to it, there appeared to be a screen displaying the time in digital format and a sound adjustment icon in the upper right corner. The mouse was active, but I could not get anything to change no matter what I tried. Even the keyboard seemed to be unable to do anything. There was a series of arrows from the middle of the bottom part of the screen. They would appear, one after the other in an upward column and then go away. There was no way to recover, so I reset the computer again and got my regular logon screen back. Evidently, there is a flaw in the system with some sort of what might be called a screensaver program. This shows yet another way that Fedora is not stable as it should be.
Okay, I just tried simplescan again and the system froze. I am attaching the output from dmesg.
