Please tell me if I did something stunningly stupid... BREAK is an RS-232 signal that you'd send over the serial console. (I am assuming here that you've been instructed to use SysRq functionality after a crash). To do it at the keyboard, try Alt+Stop+p. If you have magic sysrq enabled and that doesn't work, file a bug on the Linux kernel documentation. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

BREAK is an RS-232 signal that you'd send over the serial console. Right, but sending a break via serial console to a sparc is the same as pressing stop+a - it'll return you to the OBP's prompt. Walking to the keyboard to press alt+stop+p is is a bit annoying if the machine is not next to you. -- Bernd Zeimetz [EMAIL PROTECTED] http://bzed.de/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Walking to the keyboard to press alt+stop+p is is a bit annoying if the machine is not next to you. If you can't switch the Sun to the alternate break sequence, then send a break followed by a p to the serial console and get the same result as SysRq+p on a PC or break+p on a PC's serial console, then I agree that something is suboptimal. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Same thing here, if I managed to get the ok prompt at all, I was not able to enter anything. :( -- Bernd Zeimetz [EMAIL PROTECTED] http://bzed.de/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Right now its buildd has been building for over 3.5 hours, and it has created this one process: buildd 20263 100 0.5 1941872 11472 ? RN 18:25 192:03 dpkg-query --search libc.so.6 But it keeps moving! The load was around 5 when I checked this. I went to run 'less buildd.log', but that process just stopped responding instantly. I tried stracing it, and that strace stopped responding :) The load went up to 7 after that. -- 2.

I'm not sure if those problems are related :) The register dumps would be needed if the kernel fails to initialize the CPU (as in: try to boot a non-SMP kernel on lebrun - but I guess that works well in lebrun's case). See #440720 I find it interesting though, that the machine is still accessible - but probably this was just the same here and I should have been a bit patient for half an hour or so. Unfortunately the machine didn;t want to boot the kernel I've build with a lot of debug stuff included I'll give this another try when I have some spare time. -- Bernd Zeimetz [EMAIL PROTECTED] http://bzed.de/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I used this trick to reboot the machine with unkillable processes since it won't go down by itself. Seb

Please read the following WARNING: using the libc6 from Etch on an US III machine results in a freeze (badly, as in not reacting to stop+a/break) of your system if you do things like using aptitude after becoming root by the use of su/sudo. This is not that bad with the libc6 from testing, but this is definitely NOT fixed.

BTW, lebrun.d.o, also an USIII, running 2.6.23-rc6 plus the aforementioned patch still created unkillable dpkg-query processes. Thanks for the hint, saves me the work to give it a try. Building seems to work on US II CPUs, though, and aptitude doesn't crash as described below: Outside of the chroot: - login as user != root (we're using nss-db here didn't check if that makes a difference, but I guess you have a similar setup on lebrun) - use su or sudo to become root - run aptitude -u (for example...) frozen. Running the same under strace requieres you to kill -9 the aptitude processes, but it doesn't freeze the machine. The machine doesn't freeze with a libc6 from lenny. -- Bernd Zeimetz [EMAIL PROTECTED] http://bzed.de/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
