11 The first time that I booted after the gentoo install, it told me that
12 APIC had failed on CPU0.  After that I never received that error
13 again.  I've had problems with APIC and 3ware controller card support
14 in linux before.  Maybe because this system is so hardware-dense APIC
15 is causing me problems?  I've tried disabling it, but then I get a
16 kernel panic.

39 Sounds to me like it might be a hardware/bios problem, rather than a
40 kernel issue.  I remember having a similar problem a while ago with my
41 system (with less RAM of course).
42
43 What mother board and BIOS are you running?  How many CPUs? Also, what
44 RAM are you using?

51 It does get past GRUB.  When it goes to load the image off the drive it
52 chokes. 
53
54 I cannot get past 31GB what so ever.  When I load it up to 32GB or
55 more, I get this problem, and when I drop back down to 31GB all is fine.
56
57 I have memory testing/burn-in equipment, which says all of the DIMMs'
58 are in perfect working order.
59
60 It reboots so fast, that I'm not aware of a way to snag the dump before
61 it reboots.  Any suggestions?

I am having a problem putting 32GB or more of RAM into my system with
85 Gentoo.
86
87 I can install Gentoo (2005.1 r1) perfectly fine even on 30GB or lower,
88 once I get up in to the OS, if I shut down the machine and stock it up
89 to 64GB, when the system comes back online, and goes to boot the kernel
90 out of the loader, the system resets itself and goes back to POST. Any
91 ideas?
92
93 I've even tried to re-compile to kernel 2.6.15.4 and that gives me a
94 panic citing an Oops! Attempted to kill init!
95
96 Let me know if you'd like more detail.

100 Does the kernel reboot itself or is it grub that chokes? Does it also have
101 the problems with 32 GB, or with 48 GB? And what about 63 (if you can
102 test that). You might also want to try to get at the output of the kernel
103 before it reboots.
