[1.] One line summary of the problem:
PROBLEM: DMA Disable by lost IRQ

####################################################################

[2.] Full description of the problem/report:
Bug in PCI IRQ routing, causes fail in detect of IRQ from SIS5513 IDE controller, this
crash system in the copy of files >300MB or serevel files (+ - 1000 files ).
I try use pci=pcibios , but no solve this problem
I easy reproduce bug with:
hdparm -d0 /dev/hda
