Problem when installing from Backtrack USB.

[arimogi]

I got problem when I'm installing Back track 4.0 final from USB. It's happened when copying files process from USB. and the error log is like here :

from syslog file:

Apr 26 20:19:14 bt kernel: usb-storage: device scan complete
Apr 26 20:19:14 bt kernel: sd 4:0:0:0: [sdb] Assuming drive cache: write through
Apr 26 20:19:14 bt kernel:  sdb: sdb1
Apr 26 20:19:14 bt kernel: sd 4:0:0:0: [sdb] Attached SCSI removable disk
Apr 26 20:19:48 bt kernel: [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0

Anyone can help to solve my problem? Thanks for the administrator for your permission to let my message put here.

Are you certain of the md5sum. Also hardware specs would be nice.

dear Archangel

Are you certain of the md5sum. Also hardware specs would be nice.

I've checked the md5sum and there's no problem, I also have installed from the same BT iso on other computer and it's working well.

I got that problem while I installed it on these specs:
Acer Extensa 4620.
Proc: Intel Core 2 Duo (T5450)
RAM: 1024 MB
HDD: 120 GB, free space 60 GB
VGA: Mobile Intel Media Accelerator X1300

I've tried both, USB boot and DVD boot, but both failed at the same error.

*ERROR* trying to get vblank count for disabled pipe 0

Thanks for the attention.
