I heard that! If you are using Rebug with the OtherOS++ modification applied to it (I am) - install Rebug Update Package 0.1. Also, when I built the Rebug with OtherOS++ using PS3MFW Builder 0.2 Portable Win32 I unchecked "Allow access to all SS services (Needed for PS3DM-utils)" in the OtherOS++ section. Can't recall where I read to do that but now I have Linux AND I can play trophy games (Tested GT5 and inFamous)...
Let me know if that doesn't help and I can try to find the thread I got this information from originally...
