Hi,

2.1.102 works great on my machine here, a p133 with 32 megs of ram
and 2 ide hdd's and one ATAPI cdrom drive. I have a question regarding a
message I get at boot up from time to time -> VFS: brelse: Trying to free
free buffer. Can someone please explain to me what that is? The log
follows:

------------------------------------------------------------------

May 11 22:28:04 librum kernel: Partition check:

May 11 22:28:04 librum kernel: hdb: hdb1 hdb2 hdb3 hdb4
May 11 22:28:04 librum kernel: VFS: Mounted root (ext2 filesystem) readonly.
May 11 22:28:04 librum kernel: Freeing unused kernel memory: 28k freed

May 11 22:28:04 librum kernel: Uniform CD-ROM driver Revision: 2.12
May 11 22:28:04 librum kernel: VFS: brelse: Trying to free free buffer

---------------------------------------------------------------------------

And off it goes, there are no problems accessing any of the partitions
and the system runs just fine.

And i would like to report a problem with rmmod -a (modutils 2.1.85). It
simply doesn't remove all unused modules, in fact it doesn't remove any
modules. Removing modules by name (like rmmod sb) works however.

What could be the problem here? thanks in advance.
