(Get the code!)
Results so far (using grub2, with manual edits to boot params to load these kernels):
### kernel 3.2.0-030200rc6
Used nomodeset as boot param.
suspend from menu does not stop system - black screen with blinking cursor on vt1, white screen on vt7 until mouse click, then could use desktop. Network non-functional.
### kernel 3.4.0-030400-
nomodeset at boot.
supend from menu does not stop system - black screen. Press of space and get blinking cursor on vt1, desktop on vt7. Network down and not recoverable using menu. Could bring up wlan0 manually but wpa_supplicant command failed to run - no conf file - so abandoned attempt.
Tried to suspend a second time. Nothing happened. dmesg reported
'...
gnome-control-c .... general protection ip:...
error in libglib-
...'
Suspect something due to upgrade of glibc since this kernel.
### kernel 3.5.0-030500rc1
nomodeset at boot.
suspend from menu stops system. Screen goes black and disk stops.
Press space and disk restarts. Screen stays black. Tried blind restart using shutdown command and using Ctl-Alt-Del. No response from either. Power button to restart. I think latest kernel can be restarted using Ctl-Alt-Del.
