 Also seen on IBM System X3650:
 
 The watchdog messages were ever only written to the console, so I don't
 have those, but they appear the same as already shown in this PR.

 Problem is compounded by the fact that this machine only runs -current
 via netboot/NFS root.
 
 I don't have any dmesg from a working -current as the machine is only
 rarely powered up (due to heat production/power consumption).
 
 I have a number of other machines with bnx(4) interfaces (mostly Dell),
 so they will probably behave similarly but I have no space to set them
 up for testing..
 
 There seems to be a systemic problem with PCI-X devices and/or the
 MSI/MSI-X support in NetBSD (see kern/55115).  Perhaps that in each
 case, the PCI-X device is behind a PCIe<->PCI-X bridge?
