Ah. In ide-cd.c, I can see it checking for 2kB alignment on reads;
however for writes:
/* use dma, if possible. we don't need to check more, since we
* know that the transfer is always (at least!) 2KB aligned */
info->dma = drive->using_dma ? 1 : 0;
info->cmd = WRITE;
using_dma was set on the devices in question...
/dev/hda:
HDIO_GET_MULTCOUNT failed: Invalid argument
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
Is this setting being overruled at a higher or lower level in the call?
