And then by itself 3.0.0.15.17 landed in Synaptic, not 3.0.17. Had 3.0.0.14.16 (suffix 16) already. Then when looking in the Ubuntu software centre, history, this 3.0.0.15.17 transforms into 3.0.0-15.25... Had to run Boot Manager, so the new kernel appears in the startup menu and there it's simply listed as 3.0.0-15... somehow they do not get auto-added.
If you can follow, you're miles ahead of me.  --//-- |

I have my Linux netbook with me at work so could check its OS version. It shows as
----------------------------------------3.0.0-15 This is under Xubuntu 11.10, and I ran update-manager a couple of days ago. Just last night I did an update (which included a new Linux version) on my other two machines running 11.10. I didn't pay any attention to the Linux version last night, but I'll look at them when I get home this evening.  |

Saw this bit http://www.h-online.com/security/news/item/Li...work-problem-1414033.html about a new kernel 3.0.017 to fix a [low chance] vulnarebility through IGMP (disabled in my router] and checked my Ubuntu machine to see it's still on 3.0.0.14 . Can't see 3.0.0.15 or 16 ever having been offered for upgrade, so wondered if anyone has seen it in any of the major distros? Google only pops up a result for Puppy Linux http://murga-linux.com/puppy/viewtopic.php?t=...a99f083bfa4c70e0d130ec7be --//-- I am running Lubuntu on a dual boot Win7--something wrong with the video card causing Windows not to boot correctly--so Lubuntu seems to be running fine--http://lubuntu.net/ ---kernel 3.0.0.15 at the moment   |

What's the best way to verify that trim is working under ubuntu? I nukes 11.4 and went back to 10.4. I did update the kernel so I can have trim support. Currently using a 30gb ssd. My older maxtor hard drive was starting to have issues. Pretty sure it was showing it age (6 years old). Just looking for a quick test.

Thanks Sek, your link explains it better that the one I found on ubuntu forums. It's real similar but your link is allot better.

Sek, take a look at both of those links. The second one is the one I followed. Did the test, did not come back with all zero's. When I type in discard, it looks exactly like the second link you provided. The first like shows different. Which one is it supposed to be? The techgage uses " ext4 noatime,discard 0 1
----------------------------------------The second link uses "ext4 discard,errors=remount-ro 0 1.

Don't know... just found you the articles. The first one has 'noatime' instead of default 'relatime' [which applies if not specified]. noatime disables time stamp updating of files except when they're modified. Got that set on my BOINC drive. The second one has the errors=remount-ro which is a safety if things fail... remount but in read only. Try
/dec/... ext4 noatime, discard, errors=remount=ro 0 1 the ... of course is the ssd pointer. Of course you'll have to identify the right drive to mod the line against in fstab, and that file as you know is truly a make or break at booting [which is why I keep a working copy on the usb boot stick incase I manage to lock myself out of the boot drive.. --//-- |

I use this in my fstab for my ssd:
UUID=<your disk> / ext4 discard,noatime,errors=remount-ro 0 1 Then type: sudo hdparm -I /dev/sda | grep -i TRIM It should come back with: * Data Set Management TRIM supported * Deterministic read data after TRIM |

Thanks to both of you. Will give it a shot and try the test again to insure it's working. It's a OCZ Onyx 30gb ssd I picked up a couple xmas's ago on sale. Checked to insure it does have trim support, which I started wondering after the test failed.
