IRQ problem with PLX9080

Hi all,

I’ve been developing driver for a PCI (PLX9080) card under QNX6.1.

Based on the datasheet of PLX9080, the offset 0x69 of the CSR is related to the IRQ. I set the bit 8 and bit 11 to 1, which means the IRQ of this card is enabled. After that, when I re-compile and run, I have such error message in the command lines:

simq_timer: building abort ccb
ata_start_ccb:func 10
***and the above 2 lines apeared again and again

then the system halts.

Can anybody advise me what’s the reason of the above phenomenon? Is this caused by the setting of the PLX’s CSR?

Thank you!
