[linux-lvm] unknown ioctl problems



I'm running LVM (version 1 with 1.0.7 tools) on a 2.4 system
(2.4.24-pre1, recently upgraded to 2.4.25-pre4).  When the initrd
boots (/ is an LVM filesystem, /boot is a standard block device) I see 

   lvm -- lvm_blk_ioctl: unknown cmd 0x5310

which I guess is something to do with mounting the ramdisk.

But at other times I have noticed that the machine will lock up; I'm
not sure if it's a hardware problem but lately it seems to be related
to disk activity.  I turned off screen blanking before the most recent
crash and saw no kernel oops, but a couple of repetitions of

   lvm -- lvm_blk_ioctl: unknown cmd 0x801c6d02

Is it possible that this is some sort of reasonable ioctl?  Is it
possible that this is what's crashing the machine?  How can I find out
what the system is trying do (and maybe even why)?  I don't see any
reports of exactly this problem through google, so I'm pretty lost.
