Incompatible with iaStor.sys

[rkhunter]

Hello, experts.

I work in the anti-virus company and I am engaged in driver working out. One of its possibilities is a reading of a disk on a low level. To one of versions of your driver occurs BSOD at sending on the ATA-device of command ATA_IDENTIFY_DEVICE by means of IOCTL_ATA_PASS_THROUGH_DIRECT. BSOD occurs in your driver, after sending to it of it IOCTL.
