Hi All,

 

Just installed 11A511 (GM), everything works perfectly except when I'm using USB drives (1TB,2TB, 320GB or a stick even) when I'm transferring large files or even just viewing data on the drive it will spontaneously hang...

 

Any ideas??

 

ASUS P5Q Pro

6GB RAM

2X 9500GT (Both fully working)

AppleHDA for Audio

 

no DSDT and it is a fresh install (not ontop of SL)

 

Thanks in advance

Hi again,

 

not sure if this is at all related but I noticed that I have been getting this message while starting up in -v:

 

localhost kernel[0]: 0 0 AppleUSBCDC: start - initDevice failed

 

and once the system has finally started i sporadically get these:

 

kernel[0]: IOSurface: buffer allocation size is zero
