/usr/src/sys/dev/bce/if_bce.c - MSI allocation failed!

[Ewald Jenisch]

Hi,

In one of my machines I've got a HP GE-Card ("HP NC370T Multifunction
Gigabit Server Adapter") that FreeBSD identifies as "bce".

/var/log/messages shows the following errors:

Jul 27 12:29:29 sniff-rz2 kernel: bce0: <HP NC370T Multifunction Gigabit Server Adapter (A2)> mem 0xf6000000-0xf7ffffff irq 34 at device 7.0 on pci5

What caught my attention is the "MSI allocation failed" error above.

Since I intend to use that card as an interface that wireshark listens
on I'd better make sure it works so I don't get packet loss or other
funny things.

Has anybody else seen the above message? Anything that can be done
against it - or can it be "safely ignored"?

Thanks in advance for any clue,

PS: System in question is running FreeBSD 8.1 AMD 64 on a HP serverqq
- system and kernel as per today.
