Comment 7 for bug 1592990

Hi Christian - this is my first time through raising a problem in this way. I'm still not sure when to use eMail or attach directly to the Bug 1592990 thread.

Have you seen the latest update I entered on the thread. Do you still need me to take a system dump?

Subject: [Bug 1592990] Re: HCPGIR450W CP entered; disabled wait PSW 00020000 80000000 00000000 00004502

It is a while since I tried to read those dumps.
It seems sequential CCW'S in the beginning and then switching to repeat the same CCW/SSH group all the time.

Since the one that eventually fails doesn't seem to be different of the ones before - and those repeat - I wonder if Linux is already in error/recovery retry mode before to then give up eventually.

Also I'd be curious what your vdev 0100 actually is - since it is FCP only setup.
It that an EDEV or is it the bit of initial setup of virtual hba?
Anyway attaching an output of "Q V" and a "Q EDEV ALL" and describing your disk setup in general so we could try to recreate might help.

Finally a dump of the stopped system might help to indicate its last status.
 Prep your dump disk, then after crash
 cp cpu all stop
 cp cpu 0 store status
 cp ipl <yourdumpdisk>
But given you already attached a trace you clearly know what you are doing and can use the way to dump that you personally prefer.

Title:
  HCPGIR450W CP entered; disabled wait PSW 00020000 80000000 00000000
  00004502

Status in Ubuntu on IBM z Systems:
  New

Bug description:
  zVM v6.3 zBC12 V7000 FICON SAN048B

  Installed Ubuntu on zBC12 with FICON attached (via SAN048B switches)
  using instructions at
  https://wiki.ubuntu.com/S390X/Installation%20In%20zVM.

  Installation build completed OK but IPL fails (after initial boot options appear and timeout to default) with following error message:
  HCPGIR450W CP entered; disabled wait PSW 00020000 80000000 00000000 00004502

  A trace was taken using:

  #CP TR SSCH RUN
  #CP IPL <ipldev>
  #cp tr end

  The resulting trace appears to fail at the same point in the trace on every IPL.
  Several builds have been attempted on different VMs with identical symptoms.
