Re: [Xen-devel] current unstable doesn't boot dom0 (SMP bug?)

[Ryan Harper <ryanh@xxxxxxxxxx>]

I traced my dom0 SMP boot failure (SATA controller doesn't find device)
to this changeset, digging deeper.

date:        Tue Oct 18 11:40:31 2005 +0100
summary:     Merge i386/x86_64 smpboot.c into a simplified common Xen version.
