Hi Mike,

When your Linux/390 guest is in CP READ mode, have you tried entering "B"
(for BEGIN) to see if the virtual machine resumes running?  If you have, and
your guest does NOT start running, you should see some CP error messages
about why it hasn't started - that might be a good place to start.

If entering "B" gets your system back up and running - it probably means
somebody pressed ENTER on the virtual machine console (either a logged on
console, or via SCIF) causing the virtual machine to go into a CP READ.
That's something you'll have to address with your staff if you find it to be
the case.

Subject: 2.4.17-may timer pop problems


I'm running 2.4.17-may with the no timer patch, qdio, and guest lans.

I've noticed it has the highly unfortunate tendency to just completely drop
dead with no errors on the console.  The console drops into CP READ on any
attempt to interact with the linux/390 system, and will not resume. a re-IPL
is the only route left.

No panic message or anything useful.

It doesn't seem to be load dependent - happens fully idle, happens in the
middle of compiling.  Happens doing network traffic, happens sitting there
doing nothing, happens with the console attached and with the console
disconnected (hey, it was worth a shot).  Usually happens within 15-25
minutes of IPL.

Anyone else encounter this?
