Today I installed the new fsvybrid V2.0 on my NetDCUA5. Woking, ok. Then I compiled a new kernel to activate the matrix keyboard. This leeds to a kernel - oops while booting. I changed the kernel configuration back to not using the matrix keyboard, this kernel is working ok. I tried a few more configs, diaable or enable several rows/columns, disable or enable the SPI port - always the same result: whenever the matrix keyboard is enabled, the kernel crashes during boot. Following is the Backtrace of the kernel:
