Re: System Freeze (update)
Hans,
I recently posted a similar freeze issue. In my case I had made many changes
in a short space of time (xorg 7.1, kernel 2.6.18.x, from linuxant's
driverloader to ndiswrapper).
After weeks of testing I have confirmed that, for me, the source of my freezes
is also wireless related. It is ndiswrapper 1.28 (with a Broadcom BCM4318 and
64 bit windows NDIS drivers). So, sadly, I'm back to using Linuxant's
driverloader (which is rock-solid stable) and my freezes are gone.
BTW I had at least one response to my previous post where the poster confirmed
the source of his freezes was the bcm43xx kernel module. This seems to agree
with your findings. Hope this helps.
