I can't seem to locate where the equivlaent of arch/i386/kernel/setup.c has the vmalloc= option on arch/um though has anyone hit something like this before each of the bitmaps should only take about 60M of memory and at this point I have only tried to allocate 1 for a single 250G ubd device This will present a larger problem when I get everything working and try to allocate all 10 drives worth of bitmap ~600M I suppose I may have to go back to the paged bitmap logic but it is still a mess... The multiple major numbers and C:H:S from mconsole do seem to work correctly though ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
