[Bug 1040557] Re: UEFI boot live-usb bricks SAMSUNG 530U3C, np700z5c laptop
Samsung have published a BIOS update, version 1.0.0.3, which should correct the underlying problem. So possibly the Linux installation procedure could now be amended to: a) check whether the computer has a samsung bios lower 1.0.0.3, and if so warn the user to upgrade, and if the user continues the installation, to deactivate the samsung modules, b) if the bios version is 1.0.0.3 or higher to do the installation with the samsung modules. Knowing that Samsung are quite committed to Android and Linux, it is good that they have picked up this issue seriously and addressed it, even though it required multiple parties to do so and therefore took a bit of time.

Not sure. I guess you are referring to the BIOS signatures. Actually I just noted that the version number I gave above is INCORRECT. That is the number shown on the Samsung NL site, but that version is dated 6 March 2012 (Twelve) so is an old version. The Samsung Windows update tool, however, did install an updated BIOS yesterday evening which does not yet show on the site, as well as updates for Windows from NVidia and wireless drivers. Currently in the process of backing some stuff up, but looking in the Windows Registry (start regedit.exe, look under HKEY_LOCAL_MACHINE/HARDWARE/DESCRIPTION/System/BIOS) the BIOS shows as: BIOSVersion: P05ABJ, BIOSReleaseDate 9 March 2013, BIOSVendor Phoenix Technologies, SystemFamilly ChiefRiver System, SytemProductName 700Z3C/700Z5C, SystemVersion 0.1. I guess the BIOS release date may be the better indicator whether you are up to date, as the BIOS identifiers seem to be different than those mentioned above which may be due to subversions for different markets or something like that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Bit frustrating to not be able to correct my previous post with respect to the incorrect version number 1.0.0.3. The correction version number is not completely clear, but the version date should be MARCH 2013, just to be clear. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I don't know the full details, but believe the bug was triggered by part of the BIOS which came from an OEM for part of the hardware in these computers. If that is the case, it could be the same bug. What makes this bug so critical to fix is indeed that it is not Ubuntu which is the cause, that it can be triggered from user space. Probably these BIOS have a recognizable fingerprint, and therefor this vulnerability could be exploited with just a few lines of code to specifically target whole series of computers. So best to certainly raise awareness with Lenovo and make sure they figure out whether it is indeed the same issue, or a similar issue, and get it fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Good news I think. Today I understood from Samsung here in the Netherlands, who went out of their way to follow up on my request for information / action on this issue, that together with their partners on the bios hardware drivers they are hard at work at addressing this. They hope to have a BIOS update out shortly (within several weeks). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for that post Jean-Louis. That is good information I think. I had already sent a link to this thread to Samsung customer support in the Netherlands to alert them to this and request a quick fix from them but have not seen anything back yet except receipt confirmation. I have now also forwarded the link you posted to them again stressing the need to fix this BIOS asap. Maybe others can also alert Samsung support in their countries. They have known about this problem for quite a while now and really should expedite a fix if they want to continue to sell well, particularly as they otherwise do support Linux and Android quite strongly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1040557] Re: UEFI boot live-usb bricks SAMSUNG 530U3C, np700z5c laptop
I just got a Samsung series 7 chronos 700Z5C-S02 with the intent of installing XUbuntu 12.04 on it dual boot with Windows 8 (still can't completely dump Windows as I need to be able to work with MS Access regularly). Luckilly I ran into this series of posts before succeeding in starting to attempt install. Having read through the chain I do still have some questions and suggestions: 1) This seems to be a BIOS bug in a small number of Samsung notebooks. Has it been brought to the attention of Samsung with a clear message that they should bring out an updated corrected BIOS immediately? This bug sits at the level of the batteries in the Boeing Dreamliner, and from a simple European perspective could be seen to limit the free choice of consumers for an operating system (anti-competitive). 2) In Val's post 116 I read To install 12.04, get one of the latest daily builds from http://cdimage.ubuntu.com/precise/daily-live/current/ (dated January 18th, 2013 or later) and install from it in a usual way. . Does this mean that I can download a latest daily build and install it without having to turn UEFI, secureboot or fastboot options off without risking trashing the BIOS, can just burn this latest build to a DVD or install it on a USB stick, reboot from that and install?? 3) With such long chains of posts it becomes quite difficult to figure out what the critical posts are. It might be a suggestion to have a sticky post at the top or bottom which summarizes the current status of such a critical bug, and provides a simple cookbook for the workarounds for such dummies like me, along the lines of For (L/K/X)Ubuntu 12.04 follow the following steps: a)..., b)..., c) In addition make sure you do NOT upgrade to 12.10 until such time that this warning has been amended. For (L/K/X)Ubuntu 12.10, noting that this is not recommended for general use, follow the steps in post 116.@ ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
