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):
