Hi, Sometimes I see "re0: watchdog timeout" message on my amd64 PC.
bios0: ASRock A88M-G/3.1 cpu0: AMD A10-7860K Radeon R7, 12 Compute Cores 4C+8G, 3593.88 MHz re0 at pci3 dev 0 function 0 "Realtek 8168" rev 0x06: RTL8168E/8111E (note: re0 is not A88M-G on-board controller, added PCIe board) I suspect this caused by MSI interrupt so I tweaked if_re_pci.c like this: --- if_re_pci.c~ Sat Mar 12 03:00:48 2022 +++ if_re_pci.c Sat Jun 11 19:35:17 2022 @@ -159,7 +159,7 @@ } /* Allocate interrupt */ - if (pci_intr_map_msi(pa, &ih) == 0) + if (/*pci_intr_map_msi(pa, &ih) ==*/ 0) sc->rl_flags |= RL_FLAG_MSI; else if (pci_intr_map(pa, &ih) != 0) { printf(": couldn't map interrupt\n"); After this modify, I do not see "watchdog timeout". I want to know how many people see this timeout of re(4) and that is solved by this MSI tweak. Or, please tell me if there is any other workarounds.
