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

}
/* 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.
Regards,
