Strange messages with 2.4.16

Strange messages with 2.4.16

[Erik Tews]

Hi

After having bootet 2.4.16 vanilla on an dual piii-system, I saw the
following messages:

invalidate: busy buffer
invalidate: busy buffer
invalidate: busy buffer

They appear during the execution of vgscan. The same kernel on an other
machine with the same version of userland-utilities for lvm but other
hardware doesn't show anyone of these messages. What do they want to
tell me? Has anybody else seen this messages?

I can give you an detailed report about the hardware I am seeing this
messages on if intrested.

I see them during shutdown (or reboot); a quick grep shows that
they are coming from fs/buffer.c: invalidate_bdev().  My kernel
is with RAID-1, and without lvm.

i get it _sometimes_ after a hdparm -t /dev/md0 which is a software RAID-0 
stripe with 2 IDE hd. running 2.4.15-pre8

but no idea what it means....

Google search helps.  This was reported around 2.4.11 and Linus
says this:
