Hi Soeren, Hi all,

it seems to me that ATA TQ is working again with -current as of 
yesterday :-)

My disk is on

"atapci0: <VIA 82C686b UDMA100 controller> port 0xc000-0xc00f \
        at device 7.1 on pci0"

It's an

"ad0: 43979MB <IBM-DTLA-307045> [89355/16/63] at ata0-master UDMA100"

Even if it's obviously not reported as TAGGED, it seems to work as such:

'atacontrol cap 0 0' reports:

"ATA channel 0, Master, device ad0:

So 'write cache' is disabled and 'dma queued' is enabled, right?

At least my 'standard test' (which is a 'tar cvf /dev/null /disk/ports') 
is not able any more to switch the disk to PIO-Mode - which I tried 
repeatedly ;-)

The only thing I saw were 1,2 stops of about 500ms during the listing of 
the tar-command but nothing worse happened. With earlier Kernels this 
indicated a soon lock and switch to PIO...

Fine! I hope this stabilizes...
