As one sees, the latency for the IRQ is as high as 74 milliseconds,
Wow, that's pretty big. Did you check your disk settings with hdparm?
Especially the unmaskirq and use_dma flags?
Yes, everything seems fine:
/dev/hda:
unmaskirq = 1 (on)
using_dma = 1 (on)
/dev/hdb:
unmaskirq = 1 (on)
using_dma = 1 (on)
/dev/hdc:
unmaskirq = 1 (on)
using_dma = 1 (on)
Ciao,
Ingo.
