Hi all,

I was just wondering if there's a solution to fix the WRITE_DMA problem. I've
searched the archives but couldn't find a complete answer to this,
like why it's happening and what to do about it. I'd appreciate any help.

It seems that this doesn't do any harm to my system, but I'm not sure
because at this time the system is under no load at all. These errors just
appear from time to time. I would like to fix this before I move the
server into production.

I use 5.3-RELEASE and here's the output of my dmesg.today

atapci0: <Intel ICH UDMA66 controller> port 0xffa0-0xffaf,0x376,0x170-0x177,0x3f                                              6,0x1f0-0x1f7 at device 31.1 on pci0

Thank you very much.

Cezar
