Strange message: hde: interrupt lost

Using Acronis 8.0 Server Edition, I successfully create an image and store it on a external drive.
When booting from a boot disk, I get an error: (hde: interrupt lost)

Typical system with a Adaptec 1210SA raid controller set to a RAID 1 Mirror

Why this error

Thanx for the help

 

Hello XXwookieXX,

Thank you for choosing Acronis Disk Backup Software for Server.

If this error message doesn’t affect the functionality please ignore it. If you can not boot from CD please try the "acpi=off noapic" workaround and if it doesn't help please create sysinfo.txt file and send it to support@acronis.com along with the link to this thread (please see https://www.wilderssecurity.com/showthread.php?t=55317 for the detailed instructions). We will certainly help you with the solution.

Thank you.
