[Kernel-packages] [Bug 1529381] Re: [HP Compaq 6715s] Updating kernel renders system unbootable
This fix recently landed in linux-next, abef9ca9ff7dacb77603b2c0976e29423efded39 so should be supported in forth coming kernel releases (4.6+) -- 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/1529381 Title: [HP Compaq 6715s] Updating kernel renders system unbootable Status in linux package in Ubuntu: Fix Released Status in linux source package in Vivid: Fix Released Status in linux source package in Wily: Fix Released Status in linux source package in Xenial: Fix Released Bug description: [SRU Justification][Vivid][Wily] The kernel by default is now using 64 bit addresses from the FADT, however, some firmware has legacy 32 bit addresses that are correct and 64 bit addresses that are buggy and incorrect. This results in some machines breaking on boot. [Fix] Add a workaround kernel parameter that forces ACPI to use the 32 bit addresses from the FADT [Testcase] Without the fix, machine won't boot. With the fix add "acpi_force_32bit_fadt_addr" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, roll in the kernel and it will boot [Regression potential] This fix only twiddles the ACPI global variable acpi_gbl_use32_bit_fadt_addresses if the override flag is used on the kernel, so the regression potential is minimal as one has to force the flag to enable the feature. To reproduce (on this hardware) 1) Install 14.04.3 LTS (Ubuntu or XUbuntu) 2) Install updates 3) Reboot The kernel used after update is 3.19.0-42. Booting with the kernel that came with the install image (3.19.0-25) works fine. This computer is a HP Compaq 6715s.

[Kernel-packages] [Bug 1529381] Re: [HP Compaq 6715s] Updating kernel renders system unbootable
Verified on Vivid. Steps used: 1. Hacked seabios to extend FADT to include 64 bit X_* PM registers which pointed to garbage address 2. Boot vivid QEMU VM with old kernel and modified (broken) BIOS 3. Observe kernel failures 4. Install new kernel (3.19.0.49-generic) #55 (Jan 22) 5. Add acpi_force_32bit_fadt_addr to kernel boot line 6. Reboot 7. Observe no kernel failures. 8. Boot with new kernel and original "sane" seabios BIOS 9. Observe no kernel failures. Looks good to me on Vivid. ** Tags removed: verification-needed-vivid ** Tags added: verification-done-vivid -- 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/1529381 Title: [HP Compaq 6715s] Updating kernel renders system unbootable Status in linux package in Ubuntu: Fix Committed Status in linux source package in Vivid: Fix Committed Status in linux source package in Wily: Fix Committed Status in linux source package in Xenial: Fix Committed Bug description: [SRU Justification][Vivid][Wily] The kernel by default is now using 64 bit addresses from the FADT, however, some firmware has legacy 32 bit addresses that are correct and 64 bit addresses that are buggy and incorrect.

[Kernel-packages] [Bug 1529381] Re: [HP Compaq 6715s] Updating kernel renders system unbootable
Verified on Wily Steps used: 1. Hacked seabios to extend FADT to include 64 bit X_* PM registers which pointed to garbage address 2. Boot vivid QEMU VM with old kernel and modified (broken) BIOS 3. Observe kernel failures 4. Install new kernel (4.2.0-27-generic) #32 (Jan 22) 5. Add acpi_force_32bit_fadt_addr to kernel boot line 6. Reboot 7. Observe no kernel failures. 8. Boot with new kernel and original "sane" seabios BIOS 9. Observe no kernel failures. Looks good to me on Wily too. ** Tags removed: verification-needed-wily ** Tags added: verification-done-wily -- 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/1529381 Title: [HP Compaq 6715s] Updating kernel renders system unbootable Status in linux package in Ubuntu: Fix Committed Status in linux source package in Vivid: Fix Committed Status in linux source package in Wily: Fix Committed Status in linux source package in Xenial: Fix Committed Bug description: [SRU Justification][Vivid][Wily] The kernel by default is now using 64 bit addresses from the FADT, however, some firmware has legacy 32 bit addresses that are correct and 64 bit addresses that are buggy and incorrect.

[Kernel-packages] [Bug 1529381] Re: [HP Compaq 6715s] Updating kernel renders system unbootable
I added the "proposed" source and from there installed kernel 3.19.0-46 (using Synaptic). Booted with acpi_force_32bit_fadt_addr and system froze. I get the feeling this kernel wasn't the one I was supposed to be testing with. Could it be because I am on Trusty? Is the proposed kernel released to be available for me to test? I see the tags about vivid and wily but the problem occurs for Trusty users too. Also wondering about something Mr. Zheng wrote on the bug on bugzilla.kernel.org: "What we can offer here is to provide a quirk for your platform to revert the behavior back to favor 32-bit GAS values on this platform before your issue is root caused." Wouldn't it be nicer to also detect this computer automatically and force 32-bit registers so the boot parameter wouldn't be needed? Many people won't want to bother with boot parameters - they'll just see how Ubuntu doesn't boot on their machines and be disappointed. Or should we wait until the quirk is added upstream? -- 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/1529381 Title: [HP Compaq 6715s] Updating kernel renders system unbootable Status in linux package in Ubuntu: Fix Committed Status in linux source package in Vivid: Fix Committed Status in linux source package in Wily: Fix Committed Status in linux source package in Xenial: Fix Committed Bug description: [SRU Justification][Vivid][Wily] The kernel by default is now using 64 bit addresses from the FADT, however, some firmware has legacy 32 bit addresses that are correct and 64 bit addresses that are buggy and incorrect.

For reference: http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf, section 5.2.9 Fixed ACPI Description Table (FADT), see the 32 bit PM registers (PM1a_EVT_BLK etc) and their 64 bit counterparts (X_PM1a_EVT_BLK etc). You can check if these are sane by running "sudo fwts acpidump - > dump.log" and then checking if the 32 bit and 64 bit variants of the PM registers are different.

[Kernel-packages] [Bug 1529381] Re: [HP Compaq 6715s] Updating kernel renders system unbootable
So it's highly likely that the 64 bit addresses used for specific PM registers are wrong in the FADT, where as they are correct in the 32 bit addresses. The FADT supports old 32 bit legacy addressing for PM registers and 64 bit addressing too. Unfortunately sometimes the firmware sets the 64 bit versions incorrectly and the kernel is now using these in preference to the 32 bit variant, hence the issue. -- 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/1529381 Title: [HP Compaq 6715s] Updating kernel renders system unbootable Status in linux package in Ubuntu: Triaged Bug description: To reproduce (on this hardware) 1) Install 14.04.3 LTS (Ubuntu or XUbuntu) 2) Install updates 3) Reboot The kernel used after update is 3.19.0-42.
