Hi,
I've been getting the following for the last few weeks in -STABLE when trying
to mount a SMB share; the first attempt gives:
bash-2.05a# mount_smbfs -I server -W <domain> //user@server/share /mnt
mount_smbfs: vfsload(smbfs): Exec format error
kldstat shows:
bash-2.05a# kldstat

and I get this on the console:

Trying again, the message is different, I get
module_register: module dev_netsmb already exists!
linker_file_sysinit "smbfs.ko" failed to register! 17
on the console, and kldstat shows:

Errr. This used to work, as recently as about ~4-5 weeks ago, but has been
failing for a few weeks now. Kernel config included:
options NETSMB #SMB/CIFS requester
options NETSMBCRYPTO #encrypted password support for SMB
options LIBMCHAIN #mbuf management library
options LIBICONV
so I'm really stumped as to why the kernel is even trying to load the modules
(which are up-to-date with the kernel & userland, on a cvsup from last night,
29th July, BTW). libiconv was portupgraded, and made no difference to the
symptoms.
I read the archives, and this seemed to be a problem circa 4.5-RELEASE,
someone at that time suggested that not statically compiling NETSMB into the
kernel helped. I left only NETSMBCRYPTO in the kernel (as the other 3 have
KLMs), and got this entirely repeatable crash-on-boot (pardon typing):
Booting [kernel]...

Loading the modules into the kernel from the loader gives precisely the same
results, e.g. no boot with that kernel.
Anyone got any suggestions?
