I don't know the original posters problem, but I suspect I see something similar. On a to be embedded system with a Geode (Cyrix) CPU and with a ATA compatible CompactFlash drive I get the following messages on bootup: invalidate: busy buffer VFS: busy inodes on changed media. This seems to happen while the system tries to remount the root fs rw. My Boot messages (plain Marcello 2.4.17): LILO 21.7 boot: Loading linux.........
