In fact Ubuntu and derivative users have been experiencing issues related to that for awhile as they dropped support for non-pae kernels since 12.04. (I was running Lubuntu 12.10 on this laptop previously, but the kernel was stuck to what was in Lubuntu 11.10.) On boot non-pae systems get "This kernel requires the following features not present on the CPU: pae Unable to boot - please use a kernel appropriate for your CPU.". Funnily enough, merely 20 minutes after I posted here, someone posted a reply on Ubuntu-users to someone else's issue about Lubuntu's 12.10 generic kernel not booting. The replier says a pae kernel can boot and run fine on a non-pae cpu if the cpu *reports* it can do pae. There's apparently a tool (fake-pae) that puts the string "pae" in /proc/cpuinfo. I know I'm not running fake-pae, yet it still boots, so I'm wondering if Debian has done something to the kernels to not check the cpu flags? I note Dom's Pentium M system doesn't have pae in flags either (Though his Celeron does, which it should anyway.). > My laptop shows: > > model name : Intel(R) Pentium(R) M processor 1600MHz > flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov > clflush dts acpi mmx fxsr sse sse2 tm pbe up bts est tm2 > > and an even older laptop gives: > > model name : Celeron (Coppermine) > flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov > pse36 mmx fxsr sse up > > Both running the 3.2.0-4-686-pae kernel > -- PaulNM -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
