I've a similar problem. My machine has only 768M RAM but I think it may be
related. I've 4 IDE disks making up a MD raid5. This md is a single PV in a
VG. If I copy some amount of data (mostly from about 2-4 gigabytes) to a LV
created in that VG the complete system locks up, no chance to press
ctrl-alt-del, only hard reset works.
If someone has a solution for this please help.
BTW: I'm using LVM 1.0.7
