http://bugzilla.opensuse.org/show_bug.cgi?id=1161959 Bug ID: 1161959 Summary: When compiling software on SSD, the whole system hangs Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: scorched@bk.ru QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hello, my desktop Leap 15.1 system is installed on HDD, but I also mount a SSD, connected via SATA. When compiling software for freelance work on the SSD, the whole system hangs (except the compiler): mouse hangs for long periods, cannot open Xfce menu, cannot open terminal app. There are only short times when the system becomes available. By searching in the internet I found an advice to use 'noop' I/O scheduler instead of 'deadline' (default for SSD in openSUSE), and this solved the problem for me. Here's what I did - in /etc/udev/rules.d directory I created a .rules file with following contents (which applies to all SSD, while leaving HDD on 'cfq' scheduler): ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop" I wonder if it's possible to solve this problem for all future openSUSE users by default? -- You are receiving this mail because: You are on the CC list for the bug.
