| |
Recently, I have had occasion to build a system on a floppy for a 4MB machine that we use as a router. In the past, the kernels that we have listed something like 400kB as the amount of memory "reserved" when they boot. Now, they claim to reserved 4MB when configured with CONFIG_HIGHMEM4G and 2MB when configured with CONFIG_NOHIGHMEM. The initial ramdisk then does not have enough space to decompress and the system halts (out of memory and no killable process). I am tracking this down and fix it (because the problem of building a small system has broader application than just this box). My current suspicion is that it is some problem with the "bootmem" changes of about six months ago. However, I thought I should post this message, in case there is some reason why the kernel really does need have to reserve all of this memory and that I should not try to change things back.
