Device 0800). Machine has 2 expanders 10 SATA disks each and 2 SAS drives connected directly. pm80xx ----- port0 (3 phy's) ---> exp0 ---> SATA, ..SATA, SES enc0 * works \---------- port1 ---> SAS * works \--------- port2 (3 phy's) ---> exp1 ---> SATA, ..SATA, SES enc1 * does not work \-------- port3 ---> SAS * works If CONFIG_SCSI_SAS_ATA is not enabled, machine only discovers 2 SAS drives and works correctly. When it's enabled kernel runs out of reserved task tags and never finish the discovery. Both expanders have the same sas address, but they are connected to different ports. If I pass "libata.dma=0 libata.force=noncq" and with bellow changes kernel is able to detect drives on the first expander, drives on the second expander are detected by the link layer but they all fail to complete ata IDENTIFY commands.
