Yeah unless I want to use tools that are not available on (minimal) install media but are available on my installed os. But anyway... just rebooting with install media and getting to the partitions is most of it... but done now and need no more comment.

And yes I am booting off of a reiserfs and have been doing so for at least 2 yrs. I haven't seen this problem in that time. Does the machine have a serial port and do you have access to a second machine that you could capture and save the early boot messages? That might be helpful. I know many machine now don't support that. There may be ways to do something similar over the network or USB if the boot gets that far. No serial port

I understand, and I'm not suggesting it was the problem. Just asking questions. Keep in mind that I ran xorg-server with the Intel driver for 4 years and the recent xorg-server/driver updates totally broke it. I couldn't wait for a fix (wife's computer - we know who really runs this place...) so I bought a new cad and moved on. Is this the same old ReiserFS that you've been running? It's not the new fangled versions is it? It sounded like the time your boot goes crazy might be when everything is getting mounted? Is that about the right time? What do you think the last message is that's good? Does the machine have a serial port and do you have access to a second machine that you could capture and save the early boot messages? That might be helpful. I know many machine now don't support that. There may be ways to do something similar over the network or USB if the boot gets that far. No serial port Yeah, I understand. I wonder what the kernel devs use these days for this issue? I know with my machine, which has a serial port, I was able to capture some stuff for Ingo Molnar that helped him out, but I couldn't do it today on 6 of the 7 machines in my house. Cheers, Mark

Just hunting for clues. Do you have a digital camera? If so maybe it's fast enough to capture the screen while it's scrolling and make the message semi-readable even though they aren't to your eyes?

Just reporting some kind of fix here. I downgraded to 2.6.29-r2 kernel from `r5' and built it from my old .config from a different system. (with a few changes in accord with the difference in the kernels [ 2.6.28 to 2.6.29-r2 ]. On reboot it just worked no endlessly scrolling text. So maybe its someting related to 2.6.29-r5 kernel or related to building that kernel with genkernel. At any rate, it seems a bit too opaque of a problem to continue trying to sort out, now that I got something working. Thanks for the tips posters.

Then there's also interactive boot feature. Just press I as soon as you see first gentoo [ok] messages and the boot will proceed step-by-step asking about every init script encountered. In baselayout-2' rc.conf there's option rc_interactiveto enable it. I believe it was in baselayout-1 as well, but you can try upgading to 2 if it's not there. If that won't work try passing init=/bin/bash as a kernel parameter (from grub) to drop right into shell on start, then do ls /etc/runlevels/boot and try starting each script one-by-one until one of them fails like you described. I believe there's also 1 or single parameter, that can instruct init not to proceed past the first runlevel, which might be a cleaner way than init=/bin/bash, but might as well try to start the same faulty script if it's encountered early enough. And then there's a low-level hack w/ sysrq key (SysRq-K, if i recall correctly) to drop into shell, which can be used at the same time as I mode I've described above. You can try disabling one of the scripts mentioned at the beginning of linked log file (my rc.log) by removing +x from them (just removing symlink from runlevel probably won't do, since other scripts might start it as a dependency) to see if boot proceeds a bit further w/o mentioned crash. rc.log: http://dpaste.com/53552/ -- Mike Kazantsev // fraggod.net signature.asc Description: PGP signature
