Hi, I'm writing from FreeBSD 10-RELEASE x86_64, installed on a Lenovo ThinkPad T430 2349H3G (SKU Number: LENOVO_MT_2349) with BIOS version G1ET99WW (2.59 ). The APU is an Intel(R) Core(TM) i5-3210M, and I don't have a second/dedicated gpu installed. I can enter ACPI s3 successfully, both with "acpiconf -s 3" and "zzz". I can also resume from S3, but I only get a blank/black screen. The system however is correctly working, I can see disk activity by running a find on /, and I can create arbitrary files (and invoke 'reboot', too). I then installed xorg and gnome2, to try if the problems persists also with an X session running. I can't switch back to a tty with xorg running, and yes, the problem is still present. Moreover, when entering ACPI S3 from X/gnome, I can see the status led blinking like in a kernel panic before S3 is entered. The wiki reports the entire ThinkPad T400 series as working fine both from a text console and from an xorg session, and resuming without problems. How can I help pinpointing the issue?
