Public bug reported:
This problem occurs with the most current snapshot of Hoary (kernel
2.6.24-14). The machine is a Shuttle SN95G5 nforce3 chipset with an
Athlon64 X2 processor. The video card is an Nvidia GeForce 7600 GT.
This is a desktop machine with a wired LAN connection.
I can suspend to RAM and hibernate and both processes appear to finish
properly. However, when I then try to resume, in both cases I get the
same result. The screen stays black and X never displays. The machine
is not entirely dead, though, because the HDD light blinks every 5-10
seconds. Also, if I press CTRL+ALT+DELETE, I get a flurry of disk
activity and then it goes back to the 5-10 second blinking.
Fortunately, I can use the Magic SysRq key combos to sync, unmount, and
reboot the machine. The network is not active during this and I cannot
SSH into the machine or even ping it.
These results occur using the binary Nvidia driver. I did try using the
nv driver as well, but it was a couple weeks ago and so it isn't quite a
fair comparison. In that case, resuming from a suspend did actually
hang the machine requiring a manual reset. I was able to successfully
hibernate and resume the machine with the nv driver, however.
I really hope I can get this issue resolved as it is one of the only
features not working with the latest Ubuntu on my system. I have not
specified a package for this bug as I'm not sure if it should go against
the kernel, the Nvidia driver, pm-utils, or something else.
