Unfortunately, I can only provide a "me, too".
I have got a Thinkpad T510 (i7-620M, 4GB RAM, Nvidia NVS 3100M) on
8-STABLE amd64 with exactly the same issue. I did compare your dmesg and
sysctl with mine -- everything but the graphics is practically the same
(you got ATA+ZFS, I got AHCI+journaling UFS, I enabled hda, C2 states,
and changed the clockrate). What could be interesting:
- The issue does not seem to be due to the on CPU graphics. It happens
with the proprietary Nvidia driver, too.
- The issue does not seem to be due to amd64. In the beginning, I had
i386 installed and saw the same.
I also installed the latest BIOS ("BIOS: 1.18 / ECP: 1.10") a few days
ago hoping that this would be it: "(Fix) Fixed an issue where system
might not be resumed on non-Windows ACPI OS." Unfortunatelly, nothing
changed.
BTW: Since your laptop is so similar, the March/April thread I started
"Thinkpad T510: LAN? CPU-C3?" probably applies to you, too. Most
important: What FreeBSD calls C2 is probably C3, which you might want to
activate.
Cheers,
Jan Henrik
