still have ad4: FAILURE - already active DMA on this device

[Dikshie]

Dear all.

upgraded to -CURRENT on 14 June 2004 (West Indonesia Time)
I got error messages;

 ad4: FAILURE - already active DMA on this device
 ad4: setting up DMA failed
 ad4: timeout sending command=c8
 ad4: error issuing DMA coammand
 ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=14610207


to solve this problem temporary I turn off dma with add hw.ata.ata_dma=0:
line to loader.conf BUT turn off ata DMA make my freebsd box 
become very slow :-(

are there any permanent solutions ? 





with best regards,
