Hi Storm, > $ sudo cat /dev/vcsa > cat: /dev/vcsa1: No such device or address
That error is errno ENXIO, see errno(3).
One view of the kernel source code has vcs_open() return that errno
under some conditions, but I can't help more than that.

if (currcons && !vc_cons_allocated(currcons - 1))
ret = -ENXIO;
