Thanks for explaining me what the flags do. I'm not skilled enough to create the DMA quirks but if you could give me some patches i'll test them. Also if you have any other idea on what could i test or how can i debug this it would be more than welcome.

Comment out the following two lines in ata_ahci_dmainit():

if (ATA_INL(ctlr->r_res2, ATA_AHCI_CAP) & ATA_AHCI_CAP_64BIT) ch->dma->max_address = BUS_SPACE_MAXADDR;

And you will not use 64bit DMA even if the chipset supports it. However I have not seen any chipsets supporting this fail, YMMV as usual :)

Hello Søren,

I'm triggering interrupt storms with this chipset after a few days of stressing the HD calling sysutils/stress with stress -d 10 -i 10 and in other term, doing:

while true; do dd if=/dev/zero of=BAH bs=1M count=1024; done;

Right now, as reported by systat -vmstat i have 578k interrupts in atapci and the machine is idle. Do you have any idea on how could i debug this? any advice would be much more than welcome.

Thanks a lot. Regards.
