From 59612d187912750f416fbffe0c00bc0811c54ab5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 29 Oct 2013 23:43:08 +0100 Subject: Revert "select: use freezable blocking call" This reverts commit 9745cdb36da8 (select: use freezable blocking call) that triggers problems during resume from suspend to RAM on Paul Bolle's 32-bit x86 machines. Paul says: Ever since I tried running (release candidates of) v3.11 on the two working i686s I still have lying around I ran into issues on resuming from suspend. Reverting 9745cdb36da8 (select: use freezable blocking call) resolves those issues. Resuming from suspend on i686 on (release candidates of) v3.11 and later triggers issues like: traps: systemd[1] general protection ip:b738e490 sp:bf882fc0 error:0 in libc-2.16.so[b731c000+1b0000] and traps: rtkit-daemon[552] general protection ip:804d6e5 sp:b6cb32f0 error:0 in rtkit-daemon[8048000+d000] Once I hit the systemd error I can only get out of the mess that the system is at that point by power cycling it. Since we are reverting another freezer-related change causing similar problems to happen, this one should be reverted as well.
