Q: amd64 TuxOnIce Freezes While "Doing atomic copy/restore"

I've been enjoying TuxOnIce on both my desktop and laptop for quite a while, but when I recently replaced my desktop with an AMD 64, TuxOnIce freezes while in the "Doing atomic copy/restore" process. So far, I've tried 1) hibernating from console rather than X, 2) unloading all modules, 3) disabling FrameBuffer, and 4) both swap partition and swap file methods.

I'm not sure where to go from here, and frankly I'm not sure what would be good info to include for troubleshooting. Please provide suggestions if you have any. Thank you.

Try using a newer version. I have seen reports of good results with 2.6.26-based TuxOnIce kernels.

I tried "tuxonice-sources-2.6.26", and with this, I can't even go to the "Doing atomic copy/restore" screen; the screen goes completely blank with the cursor blinking in the top left corner. The only way for me to break from there is the reset switch.

I also tried going to the single user mode (i.e. "init S") before hibernating, adding "ProcSetting extra_pages_allowance 5000" (and 10000) to "/etc/hibernate/suspend2.conf", and moduling many different things, but none worked. It would have been great if it gave me some sort of clues, but it just sat there frozen.

While I was at it, I tried x86 (32-bit) on a different partition, and what can I say, it simply worked as it's supposed to. No issues at all.

I don't do a lot of number crunching, but I really was looking forward to boldly march into the 64-bit world. TuxOnIce is a high priority item for me, so I'm rather disappointed when it works fine with x86 but not amd64.

Odd. The 2.6.26-based TuxOnIce I referenced is a 64-bit system. It uses an nVidia video card instead of an ATI one, though. No proprietary drivers were used, or even installed on the machine. The kernel has the nVidia framebuffer support compiled in. If you continue to have problems, I can try to get the exact kernel configuration for comparison.

If you have a serial port, set up a serial console, turn the kernel verbosity up, and suspend again. Perhaps you will see some debugging output or even a kernel panic on the serial console.

There are so many variables here, but, in princpile, tuxonice works just fine for many, me including, in 64-bit architecture.
Do you have sufficient swap space ? What are the kernel options you compiled the kernel with ? Is in-kernel method is chosen to be replaced by tuxonice or coexits ?

I'm rather illiterate, so I'm not sure how to go about setting up a serial console. I did suspect the swap space, but increasing it didn't make a difference.

It would be interesting to compare my kernel configuration with a working one, so if anyone would post one, I'd make a good use of it. I don't think I made many changes after "make menuconfig"; if I'm not mistaken, FrameBuffer and sound (SND_HDA_INTEL) would be all I added.

x86 handles everything I throw at it, but I still want to go with amd64 only if hibernation works.
