The eMMC in this machine no longer passes the self test. From OFW.
ok test int:0 SDHCI: Error: ISR = 8000 ESR = 1 Command Timeout, Command reg: 113a Mode reg: 13 Arg reg: 0 Recent commands (decimal): 17 Stopping int:0 selftest failed. Return code = -1
I was working on the graphics driver DMA code and saw filesystem corruption. The kernel code could have caused the corruption which led to the failure. It is possible it could have just been coincidence as well. Regardless this machine has non cleanly shutdown many times while debugging the graphics clock hardware hang and other various bugs.
