Thank you for your help. I installed:
linux-headers-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb linux-headers-3.7.0-030700_3.7.0-030700.201212102335_all.deb linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb linux-image-extra-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb and it booted OK. All Fn keys worked on first boot as before. I suspended and resumed and got my desktop back but the only Fn keys that worked were volume up/down. The mute, brightness, and suspend Fn keys did NOT work, as with 3.5 kernel after first resume. I tried to suspend again. This went a little differently than with the 3.5 kernel: now the screen went dark just after initiating suspend, instead of staying backlit and empty as with 3.5 kernel. However, as before, the system could not be resumed with a press on the power button. Alt-SysReq- REISUB did nothing. I verified this behavior two more times. In each case I had to hold the power button down for 5 seconds to recover from the second suspend after clean boot. So the problems remain with the upstream 3.7 kernel. Note that there is some discussion about the kernel boot option "acpi_backlight=vendor" fixing the Fn keys for brightness adjustment after resume: http://www.linlap.com/toshiba_portege_z930 This does not work for me. The instruction was for a close relative of my Portege Z935-P390 but not my exact model. BTW, if I blacklist the toshiba_acpi module, then the Fn key for mute works after the first suspend/resume (both 3.5 and upstream 3.7 kernels)! However, the brightness Fn keys still do not. And suspend still does not work after the first time. Removing the toshiba_acpi module and reinserting it between first and second suspend attempts does not fix suspend problem. To clarify, 12.04.1 works great with repeated suspend resume cycles, and the Fn keys come back each time. I would gladly downgrade to 12.04.1 but 12.04.1 does not support EFI boot. I am marking this kernel-bug-exists-upstream as directed.
