[Kernel-packages] [Bug 1307105] Re: Kernel install fails due PAE checks
I also ran into this problem with Xubuntu 16.04 LTS. I'm running an Intel Pentium M 735, Dothan, (2MB L2 Cache, 1.70 GHz, 400 MHz FSB) (CPUID: 6.D.6 (hex) or 06D6h or 6.13.6 (dec)). When I lookup the specification on the Intel site, then it says: Physical Address Extensions (PAE) 32-bit is available. (source: http://ark.intel.com/products/27588/Intel-Pentium-M-Processor-735-2M-Cache-1_70A-GHz-400-MHz-FSB#@specifications ) Are there any adverse effects known about the boot parameter "forcepae"? What I need to know is if the compiled stock kernel / compiler implemented work-arounds for the W25 and W40 errata* to the Dothan (stepping B1) family of processors. If that is so, then the PAE flag can be set / forced without problems. * Intel Celeron M Specification Update errata W25: Upper Four PAT Entries Not Usable with Mode B or Mode C Paging W40: INIT Does Not Clear Global Entries in the TLB Problem: INIT may not flush a TLB entry when: 1. The processor is in protected mode with paging enabled and the page global enable flag is set (PGEbit of CR4 register) 2. G bit for the page table entry is set 3. TLB entry is present in TLB when INIT occurs Implication: Software may encounter unexpected page fault or incorrect address translation due to a TLB entry erroneously left in TLB after INIT. Workaround: Write to CR3, CR4 (settingbits PSE, PGE or PAE) or CR0 (setting bits PG or PE) registers before writing to memory early in BIOS code to clear all the global entries from TLB.

[Kernel-packages] [Bug 1307105] Re: Kernel install fails due PAE checks
> Physical Address Extensions (PAE) 32-bit is available. If the pae flag is not present in /proc/cpuinfo then PAE is not enabled on your particular CPU, even if it is available for other CPUs in the same family. The CPU indicates PAE support (or not) in the result of the CPUID instruction, which is hardcoded in the processor microcode. > Are there any adverse effects known about the boot parameter "forcepae"? I have not seen any reports of adverse effects, but given the small number of users and non-extensive testing it is possible. > If that is so, then the PAE flag can be set / forced without problems. afaik those errata would not be a problem as Linux does not use PAT on Pentium M, and the TLB is cleared on init. But there may be other issues or internal errata that Intel hasn't published. Nobody knows why Intel disabled PAE for these processors. As the docs say: forcepae [X86-32] Forcefully enable Physical Address Extension (PAE). Many Pentium M systems disable PAE but may have a functionally usable PAE implementation. Warning: use of this parameter will taint the kernel and may cause unknown problems. The CPU is run out-of-spec so there are no guarantees. If this is not acceptable then the next easiest workaround is to compile your own kernel with PAE disabled (CONFIG_X86_PAE=n). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1307105 Title: Kernel install fails due PAE checks Status in linux package in Ubuntu: Triaged Bug description: [TRIAGE NOTE] When a user boots Ubuntu Live/Install media with 'forcepae' option, the option should automatically be added to /etc/default/grub, or kernel upgrades will refuse to install when they do not see pae capability in cpuinfo.

No, I was not booting with forcepae option. After installer, the system was fully operational so I didn't know there was need to add it. Notes in https://help.ubuntu.com/community/EnablingPAE didn't either suggest such, maybe instructions should be added there to help other people.

[Kernel-packages] [Bug 1307105] Re: Kernel install fails due PAE checks
I was testing the Lubuntu Trusty desktop i386 final iso file and had the message 'This kernel does not support a non-PAE CPU' when I tried to install the low latency kernel. Please make the installer (or some other program part) add forcepae into /etc/default/grub and from there into /boot/grub/grub.cfg so that it will be possible to install and upgrade kernels. The *big* problem will arrive, when new kernel versions arrive, and the system wants to upgrade to them. And we can expect quite a lot of new users who come to Lubuntu and Xubuntu after the end of life of Windows XP. Let us save trouble for these new users by adding forcepae automatically to the installed system :-) -o- Just to confirm my suggested solution, I added forcepae to /etc/default/grub and ran sudo update-grub After reboot it was possible to install the new kernel (in this somewhat synthetic case the low-latency kernel), and the computer can run with it (both kernels work). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1307105 Title: Kernel install fails due PAE checks Status in “linux” package in Ubuntu: Triaged Bug description: [TRIAGE NOTE] When a user boots Ubuntu Live/Install media with 'forcepae' option, the option should automatically be added to /etc/default/grub, or kernel upgrades will refuse to install when they do not see pae capability in cpuinfo.

Normally syslinux will boot the kernel in 16-bit mode and you would get the forcepae error message. Andy Whitcroft wrote: > If the kernel is booted, then forcepae must have been supplied This is not always true. A PAE kernel will boot on a PAE capable Pentium M without forcepae if the boot loader skips the 16-bit entry code of the Linux kernel. This is the case with a default install of grub on Ubuntu - which is why many Pentium M users who had installed Ubuntu before the switch to PAE-only didn't have any problems when they got upgraded (but later ran into problems when the check for pae in /proc/cpuinfo was added to the linux-image preinst). You can force grub to boot the kernel in 16-bit mode by using the linux16 and initrd16 commands instead of plain linux and initrd; using the 16-bit boot path seems to be preferred by upstream since then the kernel CPU checks get run, but it is probably too late for Ubuntu to switch. Daniel Letzeisen wrote: > Should the ubiquity installer do a special check to see if it's been s tarted > with forcepae Could do, the check is not hard (running pae kernel and (forcepae or no pae in cpuinfo flags). It would be nice for the user to not have to bother with forcepae; I would have preferred to enable it automatically rather than having the kernel parameter, but the x86 maintainers thought that a user should have to consent to operating their CPU out of spec. If Ubuntu were happy with assuming consent, then you could just add it to the default pae- kernel boot parameters and make the whole thing invisible to the user. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1307105 Title: Kernel install fails due PAE checks Status in “linux” package in Ubuntu: Triaged Bug description: [TRIAGE NOTE] When a user boots Ubuntu Live/Install media with 'forcepae' option, the option should automatically be added to /etc/default/grub, or kernel upgrades will refuse to install when they do not see pae capability in cpuinfo.

Yes, it would be nice for the user to not have to bother with forcepae to run computers with Pentium M and Celeron M CPUs. But I think this is a great improvement.
