Conflict: Parallels7 and Firmtek/Seritek eSATA

Since upgrading from Parallels6 to Paralels7 on my MacPro I noticed problems with my eSATA devices (SeriTek/2eEN4) connected via SeriTek/2ME4-E card. When ejecting the external volumes and subsequently switching off the hot swapable SeriTek/2eEN4 enclosure, the MacPro (OS 10.6.8) would consistently stall at shutdown or restart requiring a brute shutdown. Uninstalling Parallels7 resolved this problem. I consistently reproduced the effect several times by uninstalling and then re-installing Parallels7 in my system.

Paralells v. 7.0.14922.693616

Is there a chance that the Parralells team will address this issue? If required I can post the system log of the crash.
