=== sargas is now known as Guest95490 [01:33] I'm a noob. Can I install linux-headers-3.11.0-19-generic on Ubuntu 14.04? [01:36] anyone? [01:55] can I install linux-headers-3.11.0-19-generic on Ubuntu 14.04? [03:09] sargas: Yes [03:09] sargas: But it won't be in the 14.04 repositories, so you'd need to download it manually. [03:25] RAOF: Thanks [03:25] RAOF: I am running 14.04 on the Acer C720 Chromebook [03:26] RAOF: Trying to get it to suspend properly [03:26] RAOF: I think kernel 3.11.0 will do the job === shuduo is now known as shuduo_afk [15:40] Will dmsetup remove flush any buffers for the device prior to removing it, or should sync be run manually? If I do need to sync manually, would `blockdev --flushbufs /dev/mapper/name` accomplish what I need? For reference, I'm concerned because of this: http://www.redhat.com/archives/dm-devel/2012-January/msg00082.html Has this been patched in recent versions of Device Mapper? If so, which version? === JanC_ is now known as JanC [23:08] I finally found the reason why I was having issues (bug). It is reported as fix committed.
