Hello all,
the changes to linux/arch/i386/kernel/apm.c in 2.4.18-pre7 cause my system
to come up with a blank console after resume. The cursor is still visible,
but no text is there. Switching to another console and back fixes it.
I just verified the problem exists still with 2.4.20-rc1.
A binary search turned up 2.4.18-pre7 as the kernel which broke.
