Random system freezes since upgrading to KDE 4.6.2.
Firstly let me say thank you for NVIDIA for providing native FreeBSD drivers. This was the decision that ultimately swayed me in favor of purchasing an NVIDIA card over other ones.
I am running amd64, stable 8.2. When the FreeBSD driver first came out I was having stability problems and random crashes like many others in the forums, but these eventually stopped. I have been running stable with no issues for quite some time now.
Recently, I upgraded KDE to 4.6.2 and since that upgrade I have been experiencing random crashes again. I was using the NVIDIA driver from the ports, 256.53_1, with no issues, but since upgrading KDE things are quite unstable.
I have received crashes (complete system freezes) while doing the following:
1. Browsing in Firefox or Opera. Specifically when opening images.
2. Crashes with KDE and also with TWM. I have since stopped using KDE and have been running simply TWM to see if it was only KDE related.
3. Random crashes when viewing video with mplayer. The same video that I was playing when the system crashed plays fine on the next reboot. It seems to be very random.
What I have done to try and resolve this issue:
A. Re-synced the "RELENG_8" sources and rebuilt my system.
B. Rebuilt all ports.
C. Switched from the ports NVIDIA driver, 256.53_1, to the newest one, 270.41.03.
D. Tried to catch a kernel dump, but have been unsuccessful.
None of the above has helped and I am still "freezing". I am torn at the moment between trying to roll my ports tree back to a previous point in time where I was stable and moving on up to 9_CURRENT. Any ideas of what I could try to bring back a stable system?
Quick system specs:
Motherboard: MSI X58 Pro-E
CPU: Intel Core i7 920 2.66GHz
Graphics: Elsa Gladiac 796 GT SS (Nvidia GeForce 9600 GT)
FreeBSD Stable 8.2, AMD64
I have generated a bug report and attached it. Please note that I have not been able to do this while the system was "frozen", but it was made while the system is running normally.
