at which point basically anything hangs.  In = auto-boot it is

Anyone an = idea?


Looks like deadlock with = another thread. Anybody else in the time keeping / callout = code?

I think this is = related to the MMC driver having issues (MMCCAM or not).
If I = try to use a MMC sdcard on any of my rk35X8 boards as the disk device it = will eventually hang on first access to the MMC controlled = media.
I thought I had an issue here with my dev setup but = clealy I'm not alone :)
