[Kernel-packages] [Bug 1813873] Re: Userspace break as a result of missing patch backport
Thanks for the link Guilherme, guess that answers that question. Given March 4 is just round the corner, I am not sure there is much can be done at this point, but I will however just echo what Tom beat me to saying: As a software developer I fully understand and recognise the need to delay things for various reasons even if it may seem everything is primed and ready to go. That being said I think the overall response time here has not been great at all. A kernel regression which breaks user space programs (including the default TTY login), and has a small, tested patch available should absolutely not take 3-4 weeks to be released. I understand that this new March 4 release will have additional unrelated patches that need that testing time, but I think breaking from the standard SRU cycle to either revert the problematic patches, or apply the fix would absolutely have been worth it - just look at the 13 duplicates of this bug and the posts on various other web forums / support sites. -- 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/1813873 Title: Userspace break as a result of missing patch backport Status in linux package in Ubuntu: Fix Committed Status in linux source package in Xenial: Fix Committed Status in linux source package in Bionic: Fix Committed Status in linux source package in Cosmic: Fix Released Bug description: Hi, The most recent set of Ubuntu kernels applied a variety of tty patches including: https://github.com/torvalds/linux/commit/c96cf923a98d1b094df9f0cf97a83e118817e31b But have not applied the more recent https://github.com/torvalds/linux/commit/d3736d82e8169768218ee0ef68718875918091a0 patch.

Putatieve, Seems like you have the bionic HWE installed, so that is why your server is defaulting to 4.15.

I have used the boot param noapic to run Ubuntu on this laptop since 12.04, however acpi=off, acpi=noirq or acpi_backlight=vendor dell_laptop.backlight=0 all also fix the issue. Using the last option however causes poor brightness control as the dell backlight driver is not properly optimized.
