This seems rather generic. I recently added one entry:
{ /* Handle problems with rebooting on HP nc6120 */
.callback = set_bios_reboot,
.ident = "HP Compaq nc6120",
.matches = {
DMI_MATCH(DMI_SYS_VENDOR, "Hewlett-Packard"),
DMI_MATCH(DMI_PRODUCT_NAME, "HP Compaq nc6120"),
},
},
But your patch will do this for all HP laptops, will it not? Worrisome.
Is it not possible to identify particular models?
