Hello,
i have a Linuxppc Kernel 2.4.8 pre 4 running on a motorola asd8260 board
(16M ram). When using initrd and ramdisk to boot the system i run into out
of memory problems.
proc/meminfo shows:

        total:    used:    free:  shared: buffers:  cached:
Mem:  14958592 12062720  2895872  7421952  6656000  2191360

LowFree:          2828 kB
SwapTotal:           0 kB
SwapFree:            0 kB

is it really necessary to have so many buffers allocated and if not, how can
i change the amount?
(i already tried to change the values in /proc/sys/vm/buffermem without any
success).
Also other ideas how to optimize the ram usage are highly appreciated.

Thanks a lot for your input,
Michael
