Well, the install succeeded this time and I can't remember doing anything different than the last time... Wait, I selected Estonian last time and US English now - will retry tomorrow with Estonian.
I redid the installation in Estonian and it still worked. Also did dd if=/dev/zero of=/dev/md/0 bs=1Mfrom VT2 after setting up raid and before setting up LVM to make sure that the LVM problem does not appear again. Maybe this is somehow correlated with the failure, or since I used a netinst CD, maybe there are newe components in testing mirrors now?
