You explicitly excluded the graphic card in your patch. I have some questions about this. Why can't we reset the graphic card like other pcie devices? We have problems, if 1st kernel is in kms mode kdump kernel will have no chance to switch back to VGA console. There's no serial port on most of recent laptops thus it's difficult to debug kdump issue. So if we can reset graphic card as well, and if it works I wonder if the 2nd kdump kernel can use vga console with nomodeset? -- Thanks Dave -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
