I have this problem with 12.10 Quantal 64 bit installed on my new Toshiba Portege Z935-P390 via EFI boot: After resuming from the first suspend after clean boot, the mute Fn key (Fn-esc) no longer works and neither do the screen brightness Fn keys nor the WIFI on/off Fn key nor the suspend to RAM Fn key (I usually suspend via the menu anyway). However, the volume up/down Fn keys continue to work.
If I attempt to suspend a second time then the machine locks up during the suspend process, it appears. From the suspend logs it appears that the all scripted steps complete properly but things just hang in the final suspend step. The machine cannot be resumed from this, it must be rebooted. The same problem occurs when I boot 32 bit 12.10 Quantal from a USB key. In order to test this I must disable the EFI setting in BIOS because only the 64 bit version of Quantal supports EFI boot (it appears). However, if I boot 32 bit 12.04.1 from a USB key then I can suspend and resume multiple times. Unfortunately, I cannot easily use 12.04.1 because it does not support EFI boot, and if I leave the BIOS setting to permit non-EFI boot then I cannot run the Windows 8 that is installed on the other partition.
