Re: Kernel crashed when writing data from IDE to a SCSI card.

Hi,

These is the Adaptec card I m using in FreeBSD 5.3:
# grep Adaptec /var/log/messages

Feb 24 23:56:46 gateway kernel: ahd0: <Adaptec 29320 Ultra320 SCSI 
adapter> port 0xde00-0xdeff,0xd000-0xd0ff mem 0xff8fc000-0xff8fdfff irq 
21 at device 0.0 on pci1
Feb 24 23:56:46 gateway kernel: ahd1: <Adaptec 29320 Ultra320 SCSI 
adapter> port 0xd400-0xd4ff,0xd800-0xd8ff mem 0xff8fe000-0xff8fffff irq 
22 at device 0.1 on pci1
