(I sent a similar email out earlier in the week, but received only one
reply, so I'm trying again)

I'm repeatedly getting:

When trying to do create a snapshot with lvcreate -L10G -s -n snaptest
/dev/vg0/lv0. 

The kernel source is mildly patched with (in order)
lmsensors-patch-2.7.0vs2.4.18
i2cpatch-2.7.0vs2.4.18lvm    
lvm-1.0.7-2.4.18.patch
linux-2.4.18-VFS-lock.patch  
linux-2.4.18-sard.patch
3ware 7.5.2 drivers (copied over by hand). 

and built using  gcc --version 2.95.4

The hardware is: 

     4 gig ram, 
     2x2.4Ghz. Xeon processors (hyperthreading on). 
     6 200 gig Western Digital drives attached to a 3ware 7800 card. 
     1 200 Gig Western Digital drive attachedt to the motherboard. 
     Motherboard is a Supermicro SUPER P4DPi-G2 (MBD-P4DPi-G2-B)

I have:
# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set
CONFIG_HIGHMEM=y

I am told by the LVM Guy that this is a kernel VM bug. Is this the case?
If so, is there a patch I can apply to let me get this stuff into
production?

Mr. Babbage, if you put into the machine wrong figures, will the right 
answers come out?' I am not able to rightly apprehend the kind of confusion 
of ideas that could provoke such a question." -- Charles Babbage
