[linux-lvm] syslogd reports: kernel: lvm -- lvm_chr_ioctl: unknown command 4004fe0a

Hello guys.

This is my first time using lvm.

After using pvcreate and vgcreate I rebooted and tried to activate the
volume group.

After the reboot I found the following in the kernel log:
Jul 11 19:40:52 alderaan kernel: LVM version 0.9.1_beta2  by Heinz
Mauelshagen (18/01/2001)
Jul 11 19:40:52 alderaan kernel: lvm -- Driver successfully initialized

Okay the driver is then in the kernel. No problem... later.... in the kernel
log:
Jul 11 19:40:53 alderaan kernel: lvm -- lvm_chr_ioctl: unknown command
4004fe0a

Same same error appears I run "vgchange"

I am a bit confused about this ?

I'm  using slackware 8.0 and I'm using the 2.4.5 kernel that comes with the
bare245.i image file.

Any ideas ?
