Dear Doug,

trying to boot RELENG_4 kernel with your patches (sata_7) on our FTP I got 
kernel panic (page fault in kernel mode, pid 2, no dump possible). Hardware 
involved:

root@kucha:~# grep ata /var/run/dmesg.boot 
atapci0: <Promise ATA66 controller> port 0xa000-0xa03f,0x9c00-0x9c03,0x9800-0x9807,0x9400-0x9403,0x9000-0x9007 mem 0xed100000-0xed11ffff irq 11 at device 8.0 on pci0
ata2: at 0x9000 on atapci0
ata3: at 0x9800 on atapci0
atapci1: <CMD 649 ATA100 controller> port 0xb400-0xb40f,0xb000-0xb003,0xac00-0xac07,0xa800-0xa803,0xa400-0xa407 irq 10 at device 9.0 on pci0

ad8: 57241MB <WDC WD600BB-00CCB0> [116301/16/63] at ata4-master UDMA100

Kernel paniced just after sio0/sio1, where basic RELENG_4 starts ata channel 
probes. No serial console at the moment, alas.

Unfortunately I can't bring this machine out of service for long time; however, 
we can survive occasional reboots/crashes. What other info can I provide to 
debug this?

Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
