[15:09] <MoPac> Hello. I'm wondering if the patch for timing-induced data corruption with TRIM on Samsung SSDs is incorporated into the latest 3.19.0-XX release kernels in 15.04. I have an 840 EVO and am not sure whether it's safe to upgrade the firmware 
[15:39] <apw> 8m ... thats not long to wait
[15:39] <apw> MoPac (N,BFTL), if you know the specific patch you are talking about ... then ... we can check
[15:40] <apw> henrix_, kamal, does the above description ring a bell ...
[15:40] <apw> is that the "turn off trim for a family of drives" fix i wonder
[15:42] <kamal> apw, what above description?  (I just reconnected to irc -- no backscroll)
[15:43] <henrix_> apw: yes, it does ring a bell... checking
[15:44] <henrix> apw: kamal: it's commit 9a9324d39696 ("libata: Blacklist queued TRIM on all Samsung 800-series") which is already in vivid
[15:44] <henrix> kamal: there was a user asking if 3.19 had the fix for the 840 EVO SSD
[15:53] <apw> henrix, thanks, the logs are complete even if they anr't here to appreciate it
[15:54] <henrix> :)
[20:01] <TJ-> Hopefully we can get this SSD TRIM fix backported: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3f5da624e0a891c34d8cd513c57f1d9b0c7dadc
[20:38] <FourFire> Greetings, which is the latest kernel version which I can manually install on ubuntu 15.04 and expect it not to crash/have drivber problems?
[20:39] <FourFire> I suppose that last qualifier complicated things a bit, just ignore it (drivers) if that's the case
[20:40] <FourFire> from what I can see in the mainline repo, 4.0.9 looks like the best candidate, but I don't really know anything about kernel development so I've come here for a second opinion
[20:56] <FourFire> ok, since noone has answered me in 15 minutes I'm going to go ahead and install 4.0.9
