Hi,
I recently activated and started using the basic hvc0 terminal driver in
SLES11. Its great to lose that last dependancy on 3215 line mode when fixing
bootup problems! I'm happy with the way it's set up now, but trying to get my
brain around the console=hvc0 zipl parameter. Since I can revie
We're walking through the IBM doc "Sharing and Maintaining SLES11 Linux
under z/VM using DCSSs and an NSS" but using EDEV FBA devices instead of

Just some thoughts - after you dd them, but before you try to IPL, are you

I noticed that in my boot log (dmesg) I see a return code of -5 when reading
device features for each minidisk on this system. I am not using the DIAG
