Description of problem: Laptop freeze at the BIOS screen when some Fedora image is in USB or in DVD, I can't install Fedora Version-Release number of selected component (if applicable): Fedora 12 live cd is fine, F13,F14,F15 and F16 freeze. How reproducible: Everytime, even with LIVE CD/DVD Steps to Reproduce: 1. I create working USB stick with Fedora iso using dd command. I know the image is on the USB stick correctly copied, as I installed from it on different PC. 2. Insert the usb stick to laptop and power up the laptop 3. The laptop freeze at the BIOS startup screen Actual results: Computer freeze at the BIOS screen Expected results: Run the anaconda, get to the installer Additional info: HP 6730s, BIOS up-to-date from hp.com website Workaround: Install Fedora 12, preupgrade to latest Fedora -- takes a lot of time

It would be nice to know whether this is isolinux specific. Note that the live CD image is an "hybrid image" (it can be booted both as a CD-ROM and as a hard disk) and perhaps this BIOS doesn't grok its - a bit hackish - format.
0) Some notes for future reference. 1) Fedora-12-i686-Live.iso uses "ISOLINUX 3.75 2009-04-16". Fedora-13-i686-Live.iso uses "ISOLINUX 3.84 2009-12-18". 2) Quite a bit changed between 3.75 and 3.84: git log --oneline --no-merges syslinux-3.75..syslinux-3.84 -- core/isolinux* utils/isohybrid* a40b707 isohybrid: make the -offset option actually work d59d154 isohybrid: convert -id to a binary string 63916a5 isolinux: can't clobber edx when dx contains the drive number... 6b7aa8e isolinux: bsHidden can't be in data; it is set before checksumming e17db13 isolinux: handle systems which disables interrupts in El Torito f92916d isohybrid: make isolinux.bin and isohybrid two-way compatible 177b65b isohybrid: we are backwards compatible again, change the error msg bb519a9 isohybrid: revert to a stack format compatible with previous version e462c28 isohybrid: support booting from partition; fix CBIOS booting d4d9f19 isohybrid: allow selecting the _c and _f versions of the prefix aee4e8f isohybrid: add options, change default ptype to 0x17 4826c90 Try to HLT the processor during idle 9a70458 isohybrid: preserve MBR id in isohybrid a54e6fe isohybrid: support iso images over 2GB dfa562b ISOLINUX: set directory length correctly 3193753 Global whitespace cleanup. 3a1bc74 core: move vgafontbuf out of the zero segment 7474bc5 core: add alignz macro (analogous to "alignb") for zero-pad align

Yes, it does! 0) So now we're certain it's an isolinux problem. 1) Lukas, if you think this problem is interesting and don't mind spending a lot of time fiddling with your laptop and USB stick we might be able to pinpoint the change that broke isolinux for this BIOS (between version 3.75 and 3.84). Pinpointing that change doesn't mean things get fixed: eg, it might be a change that's important to a lot of other machines and the conclusion could just as well be that this BIOS is broken. 2) If you're happy with the workaround feel free to close this report (with an appropriate resolution, perhaps WORKSFORME or NOTABUG). Otherwise we could try to pinpoint this bug.
Paul, if you don't mind to get the answers regarding pinpointing the bug only on weekends (when I have access to that laptop), let's go for it and let's bisect the bug. I can do the testing. If you are interested, I'm interested too.

I can do the testing. If you are interested, I'm interested too. 0) My first suggestion would be to rebuild (say) the F16 live CD with isolinux from syslinux-4.05. (For testing you can drop almost everything from that live CD. You could even drop the kernel and the initrd. Since once you get past the BIOS and see that isolinux is running you're done testing. That way you'll end up with a very small iso.) 1) You have to rebuild syslinux (using the 4.05 sources) to do that. 2) If the laptop still doesn't boot with isolinux 4.05 we'll have to ask around on the syslinux mailinglist to see how to best proceed from there (eg, whether you should first try to bisect the 3.75 - 3.84 changes looking for the commit that caused this issue). 3) Feel free to send me an email if you run into problems. No need to clutter bugzilla with questions not directly related to this issue.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
