kernel panic with memory disks

Mon Aug 20 09:15:13 PDT 2007

Hello,

I do not know if this is know behavior, and I know that 6.2 panic if the 
memory disk got full,
but on 7-current the panic is before the disk got full.

Here is what I do:

mdconfig -a -t malloc -s 800m
newfs /dev/md0
mount /dev/md0 /mnt
cp 600mb.file /mnt

and here is the output:

g_vfs_done():md0[WRITE(offset=76087296, length=131072)]error = 28
g_vfs_done():md0[WRITE(offset=76218368, length=131072)]error = 28
