Hi:

Booting a Dell Latitude D620 with LATEST-i386-master.img from a
USB pen drive boots up fine with the selection screen and it
runs till it reaches the following line

. ..
isa_probe_children : probing PnP devices
. ..

The boot process  seems to then hang at this point.

Th system specs are:
Dell Latitude D620
BIOS version A05
Intel Core Duo processor
Dual Core = Yes / 1.66 GHz
DDR2 SDRAM 1280 MB
Intel 945GM Graphics
Intel Pro Wireless
60GB WD HDD

The laptop is more than 3 yrs old and i was hoping that
DragonFlyBSD should boot up fine on this device.

Q: Is there a work around to this issue ? 

An additional observation here is:

if the device is booted with 'ACPI disabled' the root mount
fails. This is identical to what i reported for Acer Aspire One.

Q: Can some of the experienced folks share their insight as to
   why disabling ACPI causes ffs_mountroot to fail ?


thanks
Saifi.
