Re: kernel blocks with low memory and syscons setting a high res mode / scrollback
:I just booted with hw.physmem=32m. I have my allscreens_flags set to -h
:4700 MODE_279. When processing the allscreens_flags in rc.d, the system
:blocks (not hangs) while booting, ^T says "no controlling terminal". No
:mode change occured. Same happened with 48m, just with a mode change,
:so I suspect it to have worked for one screen but then not for another.
It probably isn't worth persuing issues with such small amounts of
memory. The lowest I've ever tested with is 64M. Theoretically we
should be able to keep the system operational with memory set that
low, but any lower and the kernel's own kmalloc areas will blow out
available physical memory.
