[Linux-ia64] Hard "hangs" with 2.4.16

Anybody else been seeing hangs with 2.4.16+ia64-1128.diff?

I'm running on 4x Lions, some with B3's and some with C0's.
The BIOS revision is 83B. I have seen the hang on at least
4 of the systems. This is a hard hang, no kb interrupts, so
kdb doesn't help. I don't have much to go on yet. The hangs
occur in random places, sometimes at various places during
boot and sometimes after the system has been up for a few
minutes. I put an ITP (American Arium) on one of the failing
systems and it didn't fail. Stayed up all night. I moved the
ITP to another failing system and was able to catch 1
occurrence of a "hang". I'm still trying to characterize this
hang to determine whether this is the same thing I am seeing
on the other systems or just a hardware (configuration) problem.
What I saw from the ITP was that all of the processors had
apparently reset (all of their IPs had returned to the reset
vector, 0x80000000FFFFFF90 (I did have the ITP set to break on
reset, but it didn't trigger). Not much else to go on, since I
couldn't even dump any useful processor context.

Anyone else seeing this sort of odd behavior with 2.4.16 on
Intel Lion SDVs?

Thanks,
