Also, does 4.x work ok on this system with SMP and APIC_IO? Hi John ! FreeBSD 5.4 will not boot if APIC is enabled, no matter if ACPI is on or off. Hey, the tipp with 4.x was great, I downloaded a 4.11-mini-inst.iso, boot was ok, installed a minimal system, added option SMP with APIC to the kernel-config, build kernel, and SUPER: 4.11 booted with SMP from logical RAID 5 array. Then I downloaded the boot-only image from 6-CURRENT (BETA3), and tried to boot: SUPER, it looks like the kernel is allready a SMP kernel, it detects bot Xeons, started 4 (virtual) CPUs as in 4.11. At the setup-screen I viewed into partitions, sounds ok ... Hmm, reviewing the boot-log (with scroll-lock) of 6-CURRENT I "missed" something, which I've seen each boot with 5.4, so I restarted the machine with the 5.4 cdrom. Just before the mystery "amr0: adapter is busy" there are 3 lines with ata1-master - I thought it is there because there is only a cdrom installed (harddisk are scsi), but maybe ... : md0: Preloaded image </boot/mfsroot> 4423680 bytes at 0xc09dde24 ata1-master: FAILURE - ATAPI_IDENTIFY timed out ata1-master: FAILURE - ATAPI_IDENTIFY timed out ata1-master: FAILURE - ATAPI_IDENTIFY timed out amr0: adapter is busy amr0: adapter is busy amr0: adapter is busy Well, now, what to do next ? Go into production (apache webserver with perl & mysql database) on an "older" 4.11 or an really new 6-BETA3 ? Heiko -- Heiko Weber : heiko(-at-)wecos.de
