[oss-devel] SBLive driver randomly crashing Solaris snv_76

[Mario Goebbels]

Usually, once a while, during or shortly after a boot up, I had my
machine panic and reboot. I always figured it was the NVidia driver,
until I spend a few minutes on finding out how to get stack traces from
kernel crash dumps. It appears that it's the SBLive driver.

mdb output is attached.
