yea i have been messing with the driver for about a month now to try to
atleast target where the failure is, ive probably put about 25-30 hours
in now modifying the code and recompiling and testing it. best i have
gotten is to figure out its a problem with the cache becoming full and
not sending it to the system in a timely fassion and the card panicing
when the cache gets full. so yes, i have volunteered to do it and i
have been trying but my knowledge of how freebsd handles drivers and
hardware is somewhat limited since this is my first time experimenting
with them hence why im on here. also something that should be noted its
not very common for someone to be running the type of constant load that
i do on my system and thats probably why more people arent reporting
