| * popey tickles apm instead | 14:28 | |
| popey | or apw ☺ | 14:28 |
| popey | I am sat at a LUG meeting with someone who wants to install 12.04 on his Thinkpad X40 laptop. Seems a reasonable thing to want to do. | 14:29 |
| popey | Sadly 12.04 now doesn't "do" non-pae CPUs, and his laptop is a Pentium M class device - 1.6GHz, and I can't get past the installer. | 14:29 |
| popey | I have seen https://lists.ubuntu.com/archives/ubuntu-devel/2011-November/034399.html this thread, and wondered if 'orphaned' is really the response for him? | 14:30 |
| JanC | popey: according to that mail only old Pentium M (400 MHz) should be affected? | 14:34 |
| popey | well I'm looking at the boot screen of ubuntu 12.04 i386 ISO and it says unable to boot and cites pae as the reason | 14:35 |
| JanC | popey: BIOS setting? | 14:35 |
| jwi | bug 930447 | 14:35 |
| ubot2` | Launchpad bug 930447 in linux "Unable to Install Ubuntu 12.04 on Pentium M x86 Laptop due to PAE kernel" [Medium,Confirmed] https://launchpad.net/bugs/930447 | 14:35 |
| JanC | I guess I should try precise on our event box hardware one of these days | 14:37 |
| JanC | which is mostly IBM thinkpads with Pentium M's... | 14:37 |
| mjg59 | JanC: 400MHz FSB | 14:39 |
| mjg59 | JanC: Which includes the 1.6GHz ones in the X40 | 14:39 |
| JanC | ah, so that mail was not really good at describing what would be affected | 14:40 |
| JanC | hm | 14:41 |
| popey | hmm | 14:41 |
| popey | soooo, should i file a bug that this machine doesn't boot, is it expected to? | 14:41 |
| popey | or tell the guy 'tough' | 14:41 |
| JanC | we have R51 laptops mostly, I think | 14:41 |
| popey | oh, so from what mjg59 says this is expected to fail? | 14:42 |
| mjg59 | popey: The CPU doesn't support PAE and the kernel in Precise has deliberately be changed to require PAE | 14:42 |
| popey | bummer | 14:42 |
| * popey reluctantly puts mint on a USB stick | 14:43 | |
| popey | thanks chaps | 14:43 |
| mjg59 | It's really unclear why Intel didn't implement PAE on those | 14:44 |
| popey | those linked bug reports do kinda give the impression that we're losing non-PAE in 12.10 not 12.04 | 14:44 |
| popey | specifically the cut/paste from the techboard meeting in december | 14:44 |
| mjg59 | /Looks/ like precise still builds generic and generic-pae packages | 14:49 |
| popey | but the iso has only got pae on it | 14:49 |
| popey | may be able to install off mini iso | 14:49 |
| popey | or upgrade from 11.10 | 14:49 |
| mjg59 | And git implies that the generic config still disables pae | 14:49 |
| mjg59 | So sounds like the iso's been built with pae, but the kernel still supports non-pae | 14:50 |
| popey | thanks for looking | 14:50 |
| JanC | popey: should be possible to make a non-PAE remix too | 14:50 |
| JanC | (although maybe not useful immediately at the LUG meeting ;) ) | 14:52 |
| JanC | seems like there Thinkpad R51 have a non-PAE Pentium M too... :-/ | 15:08 |
| JanC | *these* | 15:08 |
| apw | popey, we are supporting non-pae on 12.04, but defaulting to -pae on 32bit, including the cds | 17:36 |
| apw | popey, but if more cpus than we had been told are affected the cd default may be wrong | 17:37 |
| popey | apw: i was kinda surprised a mainstream device like a thinkpad would be 'broken' | 17:47 |
| apw | popey, indeed. you should get a bug filed with teh machine spec, to add to the decision for the cd default | 17:50 |
| apw | popey, what is annoying is that if you support pae, then a pae kernel saves power | 17:53 |
