with ramdisk_size=16384 the error message is:
[...]
md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.
RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-28 != 32768) 16777216
VFS: Cannot open root device "<NULL>" or unknown-block(253,3)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(253,3)
There is probably an exact way to determine a valid ramdisk_size, buth
which? :-}
