I've noticed that during hard disk intensive activities such as installing applications or downloading large programs some of my components will intermittently disconnect then reconnect again.  I see this a lot from my USB keyboard because the numlock lights will flash on and off every few seconds as if disconnecting and reconnecting.  Also my internal hard drives will suddenly unmount then remount again.  Once, during the Adobe CS5 install, the drive with OS X on it disconnected and the system crashed, breaking down to a console-type screen with something like "cannot find disk 1,2" (the OS X partition) on it repeating over and over.

In Console, I see two messages repeated many times over:

kernel: 0		0 AppleUSBCDC: start - initDevice failed

and

kernel: IOSurface: buffer allocation size is zero

Has anyone else experienced this?  Is there anything I should try?

did you clean install Lion ( on a fresh formatted disk ) or have kexts from SL been mixed with Lion ones ?

you use a dsdt.aml ? Auto-generated or self edited ?

Never heard such an issue before.

Thanks for the reply!  This is a fresh installation on to a formatted partition.

I'm using the dsdt.aml specifically for my board (GA-P55-USB3 rev2) downloaded from the Tonymacx86 DSDT database.

As for the kexts, I have installed some from Multibeast 3.8: Lnx2Mac Realtek ethernet drivers, AppleHDARollback and ALC8xHDA for sound.  Do you think any of these sound suspicious?

I'm also using the JMicron *ATA kexts, but only after initially experiencing this problem to see if these kexts would fix it.  They seem to have had no effect.

I too am seeing the above two erros in my system ( GA-EP45-UD3L ) with a DSDT.aml from Tony's site and a clean install.  the only extra kexts i have used are (FakeSMC,JMicron36xATA,IOAHCIBlockStorageInjector)  I noticed the errors when I could not get my eyetv software to work

Any input would be greate!
