Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Particularly we would need more information about why something doesn't want to switch you to the console.
Please add drm.debug=0x04 to the kernel command line, restart computer, and attach
* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)
to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
This bug actually seems directly related to bug 597778. Before the issue in 597778 crops up, I switch VTs just fine, but afterwards I can't.
Only additional item is this single message in /var/log/Xorg.0.log :
[ 8994.992] Failed to switch from vt01 to vt02: Input/output error
dmesg and /var/log/messages remain the same.

Right, so I will make this bug just another symptom of bug 597778 and close this one as a duplicate.
