The problem occurs for 6-CURRENT as of 9/14. It does not occur for BETA4. I can try to narrow this down further if needed. Here's some information about the machine, which has ad4 and ad6 mirrored via ccd(4): atapci0: <Intel ICH5 UDMA100 controller> port 0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 31.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 atapci1: <Intel ICH5 SATA150 controller> port 0xdc00-0xdc0f,0xe000-0xe003,0xe400-0xe407,0xe800-0xe803,0xec00-0xec07 irq 18 at device 31.2 on pci0 ata2: channel #0 on atapci1 ata3: channel #1 on atapci1 [...] ad0: 190782MB <WDC WD2000JB-00DUA3/75.13B75> [387621/16/63] at ata0-master UDMA100 ad4: 35304MB <WDC WD360GD-00FNA0/35.06K35> [71730/16/63] at ata2-master SATA150 ad6: 35304MB <WDC WD360GD-00FNA0/35.06K35> [71730/16/63] at ata3-master SATA150 das@VARK:/home/t/freebsd/vark/src/usr.bin/systat> vmstat -i interrupt total rate irq1: atkbd0 17607 3 irq4: sio0 2 0 irq6: fdc0 10 0 irq8: rtc 734353 127 irq12: psm0 3332 0 irq13: npx0 1 0 irq14: ata0 278748 48 irq18: em0 uhci2+ 485861 84 irq19: pcm0 uhci1 2 0 irq0: clk 573674 99 Total 2093590 364
