Just a wild guess, but it sounds as though the IPL text wasn't written to the IPL volume, or perhaps it was, but to a different volume. Try IPLing from tape, and using the "dd" command to dump the beginning of the volume you believe to contain the IPL text: dd if=/dev/dasda bs=512 count=20 | od -x
You may need to mount your DASD volumes and chroot to them to get access to all those commands. Also, check your other DASD volumes in the same way. Finally, do a chroot to the root file system, and re-run zipl, and see if it complains about anything. If not, then dump the beginning of the DASD volume again to see if it looks any different. Note that you will be specifying the "whole volume" device node, not any of the partition nodes. So, use dasda and not dasda1, dasdb and not dasdb1, etc. Mark Post -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Taraka Srinivas Kumar Sent: Saturday, May 01, 2004 7:53 AM To: [EMAIL PROTECTED] Subject: Fw: Central processor is looping when 64 bit linux is IPLed Guys, Resending the same query again. I am installing 64 bit linux SuSE 8.0 in LPAR mode on zSeries. Completed all the Yast partitioning and package selection. Even installation using Yast went thru fine without any problems. When i IPL the Linux LPAR with the root dasd address, it throws the following hardware error message. An error was detected in partition LINXLPAR. Central processor (CP) 00 is looping due to switching between program status words (PSWs) that are not valid. The program status word(PSW) is 00000000000000000000000000000000 - ( 32 zeroes). Any inputs ?

Anybody aware of this bug ? Is it a problem with the way LPAR profile is customized ? We are having 2 CPUs for this LPAR. Regards, Srinivas.
