Hi, I ran the saucy-desktop-i386.iso installer in the Toshiba with 768 MB RAM, 512 MB less than what was necessary earlier today. But I ran it without zRAM, and there was no freeze :-)
So that convinces me, that it is the zRAM problem described by Leszek. I will do some more tests, but if I don't report anything more today, I stay with this conclusion.
