Hello, I've two Iwill 8way Opteron equipped with 8 Opteron 875 CPUs each. (In the past we build some systems with singlecore CPUs and they went very well)
The Problem now is that the machines crash during boot when maxcpus is greater than 8. 2.6.12-rc4 works well with maxcpus=8, with 9 or more it freezes after "Testing NMI Watchdog... OK" 2.6.12-rc5 and above have more problems even with maxcpus=4 or less very early during booting. 2.6.13-X crashes later during boot (from 2 to 16 cores it's the same behavior) The last I can so on the console (kernel 2.6.13-rc2-git4, maxcpus=2..16) is: NET: Registered protocol family 1 Using IPI Shortcut mode int3: 0000 [1] SMP CPU4 Modules linked in: Freeing unused kernel memory: 212k freed Pid: 0, comm: swapper Not tainted 2.6.13-rc2-git4-default RIP: 0010:[<ffffffff8050fc00>] After that the machines are totally freezed. With maxcpus=1 all (tested) versions >=2.6.12-rc3 are able to boot. Any hints/ideas/what ever?
