[Bug 1071209] Re: memtest86+ test #7 false positives (random number sequence error)
Users are still exposed to this bug. That the bug is fixed in the repo isn't going to help people as memtest86 is run from a liveCD or Live USB. The buggy version is still in the download for 12.10, even though it's fixed in the repo. It's also in the 12.10 secure remix. Confirmed: I downloaded 12.10 64 bit today. Memtest86+ is v4.20. The Test #7 fails with good memory- false positive. Recommend the downloads should also contain the fix and perhaps amend fix status to be more helpful? People are going to get a fresh download, create a bootable CD or LiveUSB directly from the download without involving the repo - and get the false positives. I have a problem with a machine and I've spent many hours running tests - I'd read about this bug, saw the the fix released status and initially eliminated it as a problem in my investigations. I'm sure others will do this also and assume fix released means it's in the latest downloads. Even if you use the principle of RTFM, a false status against a false positive will be a headache to work around. My impact is I have a new machine and I made the supplier send me 4x 8Gb RAM replacements which weren't actually needed, plus 26 hours testing time wasted. I would spare others that pain if I could. With my MB / RAM config I'm getting the false positive with every ram stick in any slot, so if I can help with further testing I'd be happy to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1071209 Title: memtest86+ test #7 false positives (random number sequence error) To manage notifications about this bug go to: https://bugs.launchpad.net/memtest86+/+bug/1071209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I git this bug too. Tried to figure out problems with an old computer gone instable and found memtest86+ claiming that all three RAM sticks were faulty. Then tried some good (I thought) sticks from another computer with the same result. Then tried all sticks from both computers in the second computer. Then went to my problem-free main system and found that all of my brand new memory in that computer was also supposed to be bad. Having all the RAM memory in the house in every computer I own all of a sudden gone rotten on test #7 didn't seem right at all, and I've been searching for days before I found this thread. Slipped in a 12.04 and ran memtest86+ from there and voila: no problems anymore - at least not with the sticks I know to be all right. Now, I can go back to the actual work of fixing the computer that actually has problems. But I hope this bug is fixed by the release of 13.04 because to me, this has been a real time-waster. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1071209 Title: memtest86+ test #7 false positives (random number sequence error) To manage notifications about this bug go to: https://bugs.launchpad.net/memtest86+/+bug/1071209/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1071209] Re: memtest86 test #7 false positives (random number sequence error)
Linked a branch with a fix that works for me in raring. There seems to be a couple approaches for fixing this. The Suse bug has the small change to clobber the additional register and that seems to work. While the RH bug uses the C code in test.c instead of the optimized assembler to generate the proper binaries. I took the Suse approach for fixing this bug. I noticed that there are uncommitted changes in the bzr development branch. So adding quilt didn't work so well. To build I had to do an additional dpkg-source --commit to add these changes to a patch before building. What's the proper way to do this so the package is in proper shape for patching?
