I've found a way to make my toshiba portege r100 resume.

I just edited function ata_resume() in /usr/src/sys/dev/ata/ata-all.c like
that:

      ...
      int
      ata_resume(device_t dev)
      {
          printf("a delay to be sure disks have started...\n");
          DELAY(2000000);            // delay for 2 seconds
          ...
      }
      ...

Without that delay system crashes sometimes with message "ad0: detached".

I think that would work with some other toshiba laptops.

A small problem is that the delay occurs two times, for both ata
channels, but it's better than nothing.
