Re: hda: lost interrupt

I get the same message but it apparently does not harm. I guess the
BIOS takes care of pending read/write events and shuts down after all
sectors are read/written (by DMA). However, when the CPU resumes, the
OS is still waiting for the interrupt signaling the end of the DMA
transfer which does not come because the DMA finished before the
suspend.  So maybe your laptop freezes for some other reason.  If you
modified parameters with 'hdparm', try not enabling the '-u' flag. For
testing, you can also mount all disks read-only to make sure no data
is lost.
