Here's the offending line:

I got it to compile but it won't boot - it hangs right after the
'Uncompressing Linux... OK, booting the kernel' - I'm using .config

from 51-27 (attached)


and -51-27 worked just fine? I've uploaded -29 with the -28 io-apic changes undone (will re-apply them once Karsten has figured out what's wrong).

I too had the same problem booting -51-28 on my older SMP system at home. -51-29 just booted fine.


Have I corrected the other path of ioapic early initialization, which had lacked
virtual-address setup before ioapic_data[ioapic] was to be filled in -51-28?
Please test attached patch on top of -51-29 or later.
Also on Systems that liked -51-28.

    thanks, Karsten


Karsten,

Just booted on my 2.6 dual Xeon w/HT and thus far all is well. I am still building on the older SMP system that didn't like -51-28. Will report after I try booting that one.
