Created attachment 648046 [details] 32 bit 13.2 3.16.7-24 panic screen photograph I no longer believe this invalid. In June the comment 0 machine ceased to be able to POST. I gave its behavioral history some more thought yesterday, and "re-engineered" its P9657AB-8EKRS2H motherboard, replacing 3 of its 4 2200uF 16V voltage regulator capacitors that I had previously replaced with new electrical equivalents, using 3300uF 16V instead. I was then able to boot its 32 bit 13.1, 13.2 and TW installations as when I filed this, still needing nosmp on cmdline in 13.2's 3.16.7-7 and TW's 3.19.0 in order to be able to boot without panic. Then I did zypper up on all three installations. 13.2's 3.16.7-24 still needs nosmp to be able to boot without panic, but, like Kubecek's 13.1 3.12.44, TW's 4.1.6-3 produces no sign of any boot time errors that I can see. With a HD out of another machine in the comment 0 machine, I booted 64 bit 13.1 with 3.12.44, 13.2 with 3.16.7-24, and TW with 4.1.6-1. None of them required or require nosmp to boot without any apparent errors.
