Hi Mike, You reported a zipl build problem for 31 bit: http://marc.info/?l=linux-s390&m=132307473025493&w=2 The following patch (for s390-tools-1.15.0) should fix this problem: --- From: Michael Holzheu <holzheu@xxxxxxxxxxxxxxxxxx> Subject: zipl: Do not use larl for 31 bit code The larl instruction is not available for pre z900 machines in 31 bit mode. In order to be able to compile zipl also for that machines, with this patch the larl instruction is replaced by instructions that work on older machines.
