I'm experiencing a recurring problem that I hope can be addressed in the next version of LinuxCoin: after one of my two GPUs freezes and triggers a reboot, LinuxCoin (0.2 final version) fails to identify either card and I have to reinstall everything from scratch.  My cards are not seriously overclocked (5850s @ 840 Mhz) and one or the other freezes about once a day.  Having to do a complete reinstall every day is not my idea of productive mining.

In case it helps with diagnostics, below is the error message I get when I try to run Smartcoin after a LinuxCoin reboot.  It appears to be related to OpenCL.
