| |
I was impressed by how fast 2.6.18-rc3-mm2 is under memory pressure, until I noticed that my "mem=512M" boot option was doing nothing. The two fixes below got it working, but I wonder how many other early_param "option=" args are wrong (e.g. "memmap=" in the same file): x86_64 shows many such, i386 shows only one, I've not followed it up further.
