Dear Christos, Joerg,

tried that and build a recent CURRENT kernel:

NetBSD mail.physik.uni-wuppertal.de 5.99.53 NetBSD 5.99.53 (XEN3_DOMU) #0: Mon 
Jun 20 09:41:08 CEST 2011  
root%mail.physik.uni-wuppertal.de@localhost:/usr/obj/sys/arch/amd64/compile/XEN3_DOMU
 amd64

now Linux emulation seems to work, but gives some messages I haven't seen 
before:

mail# /emul/linux/bin/ls     
/emul/linux/bin/ls: bad tag 1: [4 4, 16 4,  GNU  PaX]
/emul/linux/bin/ls: unknown note type 1163097427
avelsieve-1.0.1.tar.gz        useradd_kuempel.ldif

and syslog is full of these:

pmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
dpmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
opmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
pmap_kenter_pa: mapping already present
wpmap_kenter_pa: mapping already present

as this is a productive system (central mail server for ~200 users), I rebooted 
the RELEASE kernel immediately. Are these messages (both the one created by 
running the Linux ls and the "pmap_kenter_..." "normal"?

Thanks and best regards

   Torsten
