I run with those options enabled most of the time and I didn't change my config for any of the kernels I tested (except for running 'make oldconfig'). netconsole is not much use to me as I don't have a second box at the moment to capture output on :-( So the best I can do there is to let the box run in a plain console with the test script and then press sysrq+t when it locks and take a photo of the output (or whats left of it on the screen) if any. > But if nothing seems to really give any clues, you might just try > to restart bisection with > > git bisect reset > git bisect start > git bisect good v2.6.17 > git bisect bad 1db27c11 > > and just run the resulting kernel version for a day or two.

I'll do a days run of 2.6.19-rc2 first, just to see if it's been fixed in the mean time. If it's still there I'll try to get a sysrq+t and post that, then I'll restart bisection and give each kernel a full 24hrs of testing before concluding it is good. I'll report back as soon as I have some results. -- Jesper Juhl Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
