sata_promise - another sata dvd writer problem

Hi folks,

I'm using kernel 2.6.21-mm1 and get strange problems when connecting my new SATA DVD writer to the TX2Plus Promise controller. It works with an slightly older kernel version though. And since I couldn't figure out who is responsible for the driver I decided to post my problem here.

dmesg reads:

Then I have to disconnect the drive to continue booting. I hope this can be fixed soon.

Thanks,
