[Kernel-packages] [Bug 1813873] Re: Userspace break as a result of missing patch backport
Hi, Still present in latest i386 Bionic 18.04.02 LTS -- 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. This second patch is required to prevent a rather serious regression where userspace applications reading from stdin can receive EAGAIN when they should not. I will try to link correspondence from the mailing list archives once they are available, but for now if you have access to the linux- console mailing list you can find discussion under the thread "Userspace break? read from STDIN returns EAGAIN if tty is "touched"". I would appreciate it if this could be examined soon as it is a regression on userspace.

[Kernel-packages] [Bug 1784585] Re: CPUs stall
Hi, I have not forgotten your request to try linux-next. I’ve built the new kernel. Please be advised that I copied the current kernel config file from /boot into the build directory. Upon running make, there where a significant number of new options. I choose to let them all go through on their default setting. I’m hoping to try the new kernel this weekend, but I need to backup my system first. My laptop only has usb 1.1 so this maybe slow. You are quite correct I’m running in i386 mode. I’ve got a 64bit Ubuntu image, 18-04, on a usb drive. It would be interesting to see how booting a live Ubuntu worked. For various reasons I’m keen to install the x64 and forget about the i386. But I’ll definitely try the new i386 build first. Any comments/suggestions are welcome. -- 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/1784585 Title: CPUs stall Status in linux package in Ubuntu: Confirmed Bug description: Frequently on boot system freezes.

[Kernel-packages] [Bug 1784585] Re: CPUs stall
Hi, Firstly, this problem has been ongoing since I dug my old laptop back to life, say January 2018. I put a new SSD in before installing Ubuntu 17-10 plus updates. I later updated to 18-04, all at current latest official releases. I’m copying the full syslog output, since systems/journal failed. I’ve also am copying the last run dmesg log as the kernel reported two problems: (A) CPU stalled at around 40 seconds. (B) Page protection error W+X. I’ve removed the mainline kernel and reverted to current Ubuntu release. Hope that helps. ** Attachment added: "syslog-kernel-v4.18-rc7.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784585/+attachment/5170110/+files/syslog-kernel-v4.18-rc7.txt -- 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/1784585 Title: CPUs stall Status in linux package in Ubuntu: Confirmed Bug description: Frequently on boot system freezes.
