Microsoft's Meltdown and Spectre Patch Is Bricking Some AMD PCs (betanews.com)

Posted by msmash on from the vulnerabilities-that-keep-giving dept.

Mark Wilson writes: As if the Meltdown and Spectre bug affecting millions of processors was not bad enough, the patches designed to mitigate the problems are introducing issues of their own. Perhaps the most well-known effect is a much-publicized performance hit, but some users are reporting that Microsoft's emergency patch is bricking their computers. We've already seen compatibility issues with some antivirus tools, and now some AMD users are reporting that the KB4056892 patch is rendering their computer unusable. A further issue -- error 0x800f0845 -- means that it is not possible to perform a rollback.

    Microsoft really seems to be de-emphasizing quality assurance in the Windows product. Makes me feel real good about the forced updates of Windows 10.

      After firing the vast majority of their QA, why would they expect anything different than a massive drop in quality? They knew this would happen, but decided to do it anyway.

      The new guys at Microsoft (the veterans who have created things like Windows NT have now retired), they have not yet understood that you can not make an operating system with the same techniques and procedures they use to create web pages.

    Why does error 0x800f0845 mean rollback is impossible?

      It causes the Flux Capacitor to revert to 2D matrix transformations, creating more matrices than normal to compensate for dimension loss, which triggers overflows in the TRXR precision-damper register. Next question?

      Why does error 0x800f0845 mean rollback is impossible?

      Error 800f0845 (and similar error detail codes) generally means the post-reboot stage of the auto-installer is fubar'd and since this update apparently didn't bother to create a restore point, then you can't easily rollback unless you happened create a restore point before the auto-installer tried to install this update.

      About the only way around these types of errors is to wait until M$FT issues a new windows update troubleshooter which you will probably need to run in safe mode (which also might have to be manually downloaded on another computer depending on how big a mess they made with this original hot fix). Worst case it might involve an in-place upgrade (basically installing windows on top of itself).

    3. Re:why no rollback by michaelwigle · · Score: 5, Informative

      The problem here is that you can't initiate safe mode from a cold boot. Both of those methods require you to have a somewhat working OS to start with. If your Windows 10 crashes dead and you turn it off, there is no way to force it into safe mode during startup like you could with previous versions. This is a significant problem for techs who repair systems that have been unplugged to be delivered to a central location. Yes, you can still stick in a Windows 10 bootable disk and repair from there but you shouldn't have to.

      I just dealt with this on a computer with an AMD processor, including the 0x800f0845 error.

      Safe mode would not boot.

      After enough failed attempts, it offered me the "repair your computer" option.

      Two system restores - the most recent and the oldest, failed with the 0x800f0845 errror.

      After that, however, a "startup repair" fixed it.

      I am writing this on the computer in question.

      I have no idea if this will work on all AMD equipped computers, but it certainly worked on this one.

    'bricked' means the hardware is messed up, e.g. you can't reinstall an OS.

    I've got some old Athlon boards around I was using until last year. They're great for HTPC if you don't mind a bit of noise from the fan. They make good gaming rigs for e-sports style games if you pair them with something like a 1050 or an RX460. The boards came out after solid state caps were a thing so they last forever.

      Came here to say the same thing, if it will boot from a usb/dvd/cd/floppy/network it isn't bricked.

  6. Re:AM2+ cpus are quite old even intel system from by The+Grim+Reefer · · Score: 5, Insightful

    I currently have 4 AM2+ systems running at home and while they are old, they are more then capable for what I need them to do. They're all running Windows 7. So I'll have to look into this before allowing them to be updated.

    Processors are not like they were in the 80's and 90's. In the 1980's it was seriously expensive to update, so I didn't do so as often as I did in the 1990's. I probably updated my systems every 2 to 3 years back then. But I don't' see the need to do so anymore. Unless you are a serious gamer, or do a lot of video editing/transcoding there's no need. It's been a while since I played any games, but the Phenom 2 1100T with an NVidia 730 had enough power to keep all of the settings pretty high and no issues with frame rate. Why should people be forced to send perfectly usable hardware to a landfill simply because it's not the latest shiny thing on the market?

    The OS has to be reinstalled.

    How is that bricking?
