All autopkgtests for the newly accepted linux-gcp-5.3 (5.3.0-1008.9~18.04.1) for bionic have finished running. The following regressions have been reported in tests triggered by the package:
linux-gcp-5.3/unknown (amd64) Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1]. https://people.canonical.com/~ubuntu-archive/proposed- migration/bionic/update_excuses.html#linux-gcp-5.3 [1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions Thank you! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem in Ubuntu. https://bugs.launchpad.net/bugs/1845584 Title: intel-lpss driver conflicts with write-combining MTRR region Status in HWE Next: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux-oem package in Ubuntu: Invalid Status in linux source package in Bionic: Fix Committed Status in linux-oem source package in Bionic: Fix Released Status in linux source package in Disco: Fix Committed Status in linux-oem source package in Disco: Fix Released Status in linux source package in Eoan: Fix Released Status in linux-oem source package in Eoan: Invalid Status in linux source package in Focal: In Progress Status in linux-oem source package in Focal: Invalid Bug description: [Impact] The memory region intel-lpss-pci uses has been declared as write-combining [ 0.001728] 5 base 4000000000 mask 6000000000 write-combining This leads to the system hangs up during booting up. This is a BIOS issue, but there are some platforms on the market and users are struggling on booting up the machines. So, we may have to fix this in the kernel. [Fix] Tuowen Zhao(ztuo...@gmail.com)[1] provides a diff patch for intel-lpss driver to claim to use un-catchable memory while calling __devm_ioremap(), and it works well. But it didn't be accepted by maintainer yet. To avoid the potential impact on other machines, I add a quirk to list the machines which has the write-combining area in MTRR which overlaps with the address that intel-lpss uses, only the machines in the list pass the DEVM_IOREMAP_UC to __devm_ioremap(). [Test] Verified on Dell XPS 13 7390 2-in-1 [Regression Potential] Low, without this patch, the machine even can't boot. And the quirk only for specific machines, so the modification won't affect other machines. 1. https://bugzilla.kernel.org/show_bug.cgi?id=203485#c23 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1845584/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
