Just as an FYI, I was able to workaround the issue (temporarily until we find the fix) by using an internal version of grub (used for NIM installs). I netbooted my LPAR that was failing as above and used the on-disk conf file (well, copied it to my boot-server and used it as the netboot conf file). The system rebooted once for c-a-s negotiation, and then successfully booted to login prompt! So, I believe the issue is in the grub shipped with Ubuntu. I did a quick test of setting an nvram variable at the OF prompt (ibm,fw-new- mem-def) to true, and then booting to grub, rebooting from the grub prompt and checking the variable again. It's value was now false. The Linux kernel negotiates this value to true, so I think that's why we end up in a c-a-s loop. Assigning over to Paulo for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334793 Title: PowerVM: ubuntu-14.04 stuck in ibm,client-architecture-support reboot loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1334793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
