The IDE driver, file ide-probe.c currently contains this test do prevent hard drives and IDE-flash devices (ex CompactFlash) from co-existing on the same IDE controller.
/* * Prevent long system lockup probing later for non-existant * slave drive if the hwif is actually a flash memory card of some variety: */ if (drive_is_flashcard(drive)) { ide_drive_t *mate = &HWIF(drive)->drives[1^drive->select.b.unit]; if (!mate->ata_flash) { mate->present = 0; mate->noprobe = 1; } }
This test's assumption that a spinning hard drive cannot coexist on the same controller as an IDE-flash device is incorrect. I have a working setup with such a configuration. I don't think that the IDE subsystem should punish everyone because _some_ hardware cannot tolerate this configuration.
One solution may be to remove this test from the IDE subsystem and force users with buggy hardware to explicitly disable probing for a second device. I think the parameters hdx=none or hdx=noprobe should work for them.
