It looks like this box is being strangled by bad configuration from a previous install.
The gRC thread is the graphics rendering/remote control input thread. When it fires that warning at second 2 of startup, it means the main Enigma2 event loop hasn't returned control since boot. The user sees a spinner, can't interact, and if this persists it manifests as the freezes you're experiencing because any button press or UI event queues up behind whatever is blocking the main thread.
Fix the skin. Either install PLi-HD-FullNight manually into the image, or go into the settings (if you can get in) and switch to a skin that's actually present on OpenBH
Remove or fix the automounts. The 192.168.0.0 entry in particular looks like a mis-configured entry that should be cleaned up entirely.
Once the skin and mounts are sorted, retest.
The gAccel allocation failures may largely resolve themselves once the skin is loading properly and the main thread isn't starved at boot.
The freezes are not a hardware problem...Apparently this box is being strangled by bad configuration from a previous install.
