sata_promise - another sata dvd writer problem

[Sven Lemke]

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,

How much older? Does 2.6.21 vanilla work?

etc

Probably fallout from a mistake I made in the error decoding update.
Apply the patch below, try again, and let us know if it works or not.
