(Sorry, this is more or less a lengthy "me, too":) I am observing exactly the same on my T510 (not surprisingly, as it is basically the same with a different screen size) using Nvidia (in contract to most other recent mailing list reports, which are using Intel). >From 8.1-RELEASE to 9.2-RELEASE, suspend and resume used to work with a generic kernel (I like generic release kernels and freebsd-update) -- except for a short time, which was due to the Xorg port. Especially 9.X-RELEASE were really stable with all the hardware working after resume (maybe except firewire). After going to 10.0-RELEASE, resuming would briefly turn the screen on, but it would go back to black with the power LED continuing to blink (as it does while sleeping). After a while, I realized that I lost the non-default option ACPI_PM for x11/nvidia-driver installing 10.0. With ACPI_PM for x11/nvidia-driver, I had at least one resume with most of the hardware working: The screen was still unusable being static with colorful lines, but I could ssh into the machine over wireless. I have not had time to try 10-STABLE with vt, but from reading various reports on the lists, that is probably the only way. I hope there will be a vt enabled kernel on the 10.1-RELEAS media, if vt is going to be required even for configurations that would work just fine on 9.X (WITH_NEW_XORG=yes is very usable with x11/nvidia-driver even without vt). >From what you said, you already have ACPI_PM for x11/nvidia-driver as it is listed on the wiki. Have you? Cheers, Jan Henrik
