[opensuse] openSUSE 11.0 on Dell Precision 490: Reboot problems
Hi, We noticed that some of our Dell Precision 490 workstations do not power cycle with openSUSE 11.0. When typing "reboot" it halts but does not poweroff or reboot. One has to manually press the power button. The 490 workstations had BIOS A06 installed, but an update to A08 did not help. Other 490 workstations that worked fine previously had BIOS A00. We're preparing a migration from Suse 10.1 to openSUSE 11.0 and during the Autyast installation the system should boot 4 times. Are there any known issues about this or does someone have have a clue? I didn't find something in the BIOS settings. Bye Bernd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not being familiar with that machine, I assume its a dual processor (or core 2)? This does happen in dual processor machines (has happened for a long time) because one processor can't be sure the other processor is done. ACPI was supposed to fix this, but I've seen this in certain rare occasions on modern core 2 machines. Also seen it under ubuntu. The boot command line parameter "acpi=force" might work. Seems to work with ubuntu. You might also check that the machines have the latest bios. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks for the hint. I see that we have Precision 490 with two different CPUs: Hangs at reboot: dual core: Model: 6.15.11 "Intel(R) Xeon(R) CPU 5140 @ 2.33GHz" GOOD: quad core: Model: 15.6.4 "Intel(R) Xeon(TM) CPU 3.20GHz"

I tried it with "acpi=force". Did not help. The dual core systems hang at boot. The latest BIOS is already applied. Bye, Bernd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Are these dual processor(not just dual core)?

Actually, you shouldn't need a reboot. I've installed on a Core2 system and when it says it will reboot, kexec kicks in and restarts with the new kernel without rebooting. Only after a kernel update should a reboot be neccessary.
Are there any known issues about this or does someone have have a clue? I didn't find something in the BIOS settings.
I had a problem with my Precision 610(Dual P3/Xeon 500) where it wouldn't turn off the machine. I ended up having to clear the CMOS, and then it worked afterwards. ACPI should have corrected this, but it could be a bug. Look here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/220820 If you add: reboot=p to the boot command, then it seems to reboot ok. This was for uBuntu 32bit tho. Are you doing 32 or 64bit? I own several Precision machines. Not bad machines. Solid and reliable. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Those Dell Precision 490 with reboot problems are dual core: Model: 6.15.11 "Intel(R) Xeon(R) CPU 5140 @ 2.33GHz" Those without are quad core: Model: 15.6.4 "Intel(R) Xeon(TM) CPU 3.20GHz"

Unfortunately we need to do some reboots during the Autoyast init scripts (first because we need to change some local system users which UID/GID conflicts with users in LDAP, second after applying all patches and updated kernel)

Thanks a lot! The 'reboot=b' parameter solved this issue. It means that
reboot is done "by jumping through the BIOS"
