I followed the procedure at https://wiki.ubuntu.com/DebuggingKernelSuspend... I now have a bunch of /var/log files that show being edited in AD 1916, but there's also something that looks useful:
[ 2.032000] Magic number: 7:951:842 [ 2.032000] hash matches device ptyu8 [ 2.032000] hash matches device ptyrb
https://wiki.ubuntu.com/DebuggingKernelSuspend says that I should rmmod the second driver (ptyrb), but lsmod | grep pty shows absolutely nothing.
I'll try suspend/resume with ptyrb in /etc/default/acpi-support's MODULES list.
Is there anything else I can do that might help?
