This laptop's BIOS only offers "legacy support" enabled or disabled, both of which lead to frozen kernel. I will investigate whether the GIT tree freezes at the same point.
Perhaps you could try updating your BIOS, if possible / applicable (?)

It is just odd that up to (not including) the 2.6.21-series every kernel boots, and after that, they just freeze. I am kinda stumped here.
Hey, just try git-bisect already :-) In fact, you can first try by just reverting / un-applying that patch that you initially had a suspicion on. Or, because you've already spent some time tracking down the issue, you could simply go through the git history of that file / subsystem in question and play around reverting individual patches that you find suspicious -- but really, there's no need to try and be cute with this: you could simply do a git-bisect (say between 2.6.20 and 2.6.21) and find the offending patch (or at least the one that un-hides the bug) that makes the boot fail ... [ BTW you haven't sent your dmesg / boot-time output ... if it isn't getting saved to disk, you could try serial / netconsole, copy it by hand, or simply take a photo and post it here. ] Cheers, Satyam - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
