However, on the Optiplex 790, reboot=pci has absolutely no effect - the system still hangs after the Restarting System screen.

I'm not sure why it works on the 990 and not the 790, but it definitely does not work. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Also, someone else mentioned it worked for them with reboot=pci, but this does not work for me running Xen + kernel-xen. As far as VT-d goes, I will try enabling that; however, one of my uses for O790s + Xen is for graphics passthruough, so, eventually I need this to work with VT-d enabled. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So, at least the issue I'm having seems to be VT-d related?! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Unfortunately, however, the exact reason why VT-d on Dell interferes with Linux reboot is unknown at the moment. This is an upstream issue and I don't think we can make much progress here without involving the upstream kernel developers. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If so, can you point us in that direction? 2) If the answer to #1 is no, where upstream should we go to report this? kernel.org? -Nick -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
