Are these dual processor(not just dual core)?
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"
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.
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)
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.

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