           Summary: Freeze very early in boot process with SMP
           Product: openSUSE 10.2
           Version: Final
          Platform: i686
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Kernel
        AssignedTo: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
        ReportedBy: fkamogee@xxxxxxxxx
         QAContact: qa@xxxxxxx


This system can run SUSE 10.1's SMP kernel, but both the 10.2 installer and the
installed 10.2 system hang very quickly at boot unless SMP is disabled using
kernel parameter nosmp or maxcpus. The last line printed on the installed
system's console before it hangs is "NET: Registered protocol family 2".  When
SMP is disabled, everything seems fine, and the next line is "IP route cache
hash table entries: 32768 (order: 5, 131072 bytes)".

I have tried the kernel of the day
(2.6.18.5-SL102_BRANCH_20061223002647-default), and I have tried a number of
other kernel parameters including acpi=off, apm=off, ide=nodma, pci=routeirq,
edd=off, noapic, nolapic, init=/bin/sh... I have not found anything that lets
the system boot without disabling SMP.

There is no OOPS or PANIC or printed on screen or in any logs that I can find.
In fact I'm pretty sure it freezes before anything is written to disk at all. I
tried hooking up netconsole and got nothing at all, but I can't say for sure
that it was configured correctly. I don't have the equipment to set up a serial
console, but if that's necessary I could probably track it down.
