Tim, All,
I know there were a few tweaks involving tsak to fix the tdm.log explosion problem. After leaving TDE running overnight, I noticed the fans on my laptop pegged on. Huh? Checking top, tsak was eating 90-100% of my CPU.
What is tsak?
Why is it pegging the CPU?
Here is a screenshot of top showing the cpu use:

Want me to file a bug or you want to look at it first?

tsak is the secure attention key daemon. The high CPU usage is probably related to the debug spew that was filling your tdm.log file earlier.
What type of keyboard do you have? It would also be helpful to know if it is plugged in via USB or PS/2.

Hmm... That is a good question. I am running it on an archlinux guest in virtualbox. The setup was a standard install for linux x86_64 in virtualbox, so I didn't do anything funky. I'll have to see what vbox is doing. What standard file output would you like to see? lsusb,lspci, cat /proc/?. Let me know and I'll get it :)

Actually that's enough information for me. :-) Virtualbox emulates a PS/2 keyboard and tsak has not been very well tested on PS/2 keyboards. I'll need to load up a VM to debug this, so filing a BLOCKER bug report would be a good idea.

I use PS/2 keyboards on my physical systems and I have VMs as well. I can help test.
Might be related: I filed bug report 884. One of the bugs I noticed is even when building tdebase without tsak support (-DBUILD_TSAK=OFF), and in my tdmrc I have UseSAK=false, TDM starts with the dialog to press Ctrl-Alt-Del. That should not happen. I'd like to test further.
We could merge the two bugs into one report.

FWIW I have UseSAK=false but I still occasionally get stuck at an unresponsive SAK screen after logging out and logging in, but I don't see SAK screen after rebooting.

Filed before I got your message. We will just have to add a note that bug 884 & 898 are potentially related.
