[PATCH] libata-eh: call freeze hook before port abort

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Tejun,

This patch looks like it might work for !PMP setups, but I am not so sure about PMP.

Any comments? This should help begin addressing the problem where hardware needs the DMA engine turned off before accessing the taskfile registers -- something needed for ata_port_abort() via ata_qc_complete().

	Jeff
