Hello, I recently built a newer box that is running an Intel Xeon Quad Core X3210 processor. I cannot get the SMP kernels to work with this. I tried various things with the 4.1 branch, including i386 and amd64. The i386 branches hangs during boot, while the amd64 gets caught in an infinite loop of kernel error messages. 4.2 amd64 branch gives the same exact result for bsd.mp (infinite loop of kernel interrupt errors). Please note that the regular kernel (without SMP support) works correctly. Is there anything I can do to get SMP working with OpenBSD with this processor? FWIW, it is detected with a default install of FreeBSD 6.2. The machine is a Intel SR1530AH with a S3000AH motherboard. I would love to get OpenBSD working fully with the hardware, and not have to use FreeBSD if possible. Here are some error snippets I was able to get w/ debug options enabled: For 4.1 i386.mp, it hangs here during boot: mtrr: Pentium Pro MTRR support For 4.1 amd64.mp, it gets caught here: uvm_fault(0xd077fda0, 0x0, 0, 1) -> e kernel: page fault trap, code=0 Stopped at mpbios_invent+0x42: movl 0xc(%eax),%eax Thanks in advance for any help that can be provided. I would really like to use OpenBSD, but don't want to be running at 1/4 the possible performance I could be. PS: I do not have any ways to get output from a serial console. :( Any information I get will be limited to typing it off of the visible screen. Thanks!
