Hi team
I see various threads non freezing -not sure if this is a known cause..
My console failed to read from a memory stick with a show library and then froze when I removed the stick. The stick had not failed to read before and was only about 5% full. I powered the console down and up again and it came back up just fine (I left the memory stick inserted in the SQ drive during the power cycle and re-boot). The console was now fully operational and read and wrote to the stick just fine.
The SQ5 is on firmware
1.5.6 r4043
