Re: Soft freeze with nvidia 9500 GS and driver 180.18
I am getting the same sort of crap on my amdx86_64 running Slamd.
The fix for me is to disable RenderAccel in xorg.conf.
See how you get on.
In 'Section "Device" ', add:
Option "RenderAccel" "false"
That totally stops the similar lockups I have. OK, it makes the desktop run a bit laggy - I use Fluxbox, so that doesn't really affect me - but I guess a KDE/Gnome user would have serious usability issues.
Oh. EDIT: I forgot - enabling noapic to kernel boot line also fixes this, but then I get 100's of IRQ ERR (from interrupt 7) occurring every second - so that is no option at all.
