The following messages appear with verbose logging (hand copied): ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 [...] ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat1=0x10 err=0x10 lsb=0x14 msb=0xeb ata0: reset tp2 stat0=80 stat1=10 devices=0x8<ATAPI_SLAVE> ata0: reinit done .. reiniting channel .. reset tp1 mask=03 ostat0=80 ostat1=58 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 ata0: stat0=0x80 err=0x80 lsb=0x80 msb=0x80 [...] hptrr: no controller detected An amd64 base and kernel will be checked to see if this problem also exists using amd64. >How-To-Repeat: Boot system with SMP enabled (and apic) on ASUS P5* Motherboards >Fix: It has been hinted that there is a IRQ conflict between ata0 and apic. It is also possible that RELENG_6_* worked (unverified)... WORK AROUND: disable apic with: set hint.apic.0.disabled=1 # in boot loader... >Release-Note: >Audit-Trail: >Unformatted:
