>Description:
System use ATA-RAID1:
kernel: ad4: 76319MB <WDC WD800JB-00CRA1/17.07W17> [155061/16/63] at ata2-master UDMA100
kernel: ad6: 76319MB <WDC WD800JB-00CRA1/17.07W17> [155061/16/63] at ata3-master UDMA100
kernel: ar0: 76319MB <ATA RAID1 array> [9729/255/63] status: READY subdisks:
kernel: disk0 READY on ad4 at ata2-master
kernel: disk1 READY on ad6 at ata3-master
kernel: Mounting root from ufs:/dev/ar0s1a
Under pretty heavy disk load the system crash:
