Beta7 persisting disk problems

[Michal Stanislawski]

Hello,

I've started using FreeBSD with the 5.3 BETA4 and yesterday I've 
upgraded to beta7. In beta4 I had problems with the floppy and my second 
disk. The floppy now works correctly, but the disk is still a problem. 
Here's the relevant dmesg:

The system is a dualboot with Windows as the second OS. In Win the disk 
works. Any ideas?
