Subsequent cable plugging does set PME bit\ncorrectly, but it still doesn't get woken up.\n\nSince e1000e connects to the root complex directly, we rely on ACPI to\nwake it up. In this case, the GPE from _PRW only works once and stops\nworking after that. Though it appears to be a platform bug, e1000e\nmaintainers confirmed that I219 does not support D3.\n\nSo disable runtime PM on CNP+ chips. We may need to disable earlier\ngenerations if this bug also hit older platforms.\n\nBugzilla: https://bugzilla.kernel.org/attachment.cgi?id=280819\nSigned-off-by: Kai-Heng Feng <kai.heng.feng@canonical.com>\n---\n drivers/net/ethernet/intel/e1000e/netdev.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/e1000e/netdev.c b/drivers/net/ethernet/intel/e1000e/netdev.c\nindex 189f231075c2..9366b9d19a6f 100644\n--- a/drivers/net/ethernet/intel/e1000e/netdev.c\n+++ b/drivers/net/ethernet/intel/e1000e/netdev.c\n@@ -7351,7 +7351,7 @@ static int e1000_probe(struct pci_dev *pdev, const struct pci_device_id *ent)\n \n \te1000_print_device_info(adapter);\n \n-\tif (pci_dev_run_wake(pdev))\n+\tif (pci_dev_run_wake(pdev) && hw->mac.type < e1000_pch_cnp)\n \t\tpm_runtime_put_noidle(&pdev->dev);\n \n \treturn 0;\n", "prefixes": [] }
