sudodus, your description around the 36-bit physical addressing seems a little bit confused: "If you don't get 36 bits with a PAE kernel, your CPU has no PAE capability." - the Linux documentation states that if you can boot a PAE kernel, then your CPU has PAE. If you don't have PAE, then the kernel won't even boot.
If you think that there are some non-PAE Pentium M models (which I have not seen reports of anywhere) and want to identify them then report the family, model and stepping, you can see these in dmesg ("CPU:" line) But at the moment I suspect every Pentium M can do PAE (have you seen any reports otherwise?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/930447 Title: Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M x86 Laptop due to bug in PAE kernel, initramfs or syslinux To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
