Hi there,
after playing around with dragonfly for quite some weeks I decided
it is time to set uo a production environment and I remembered an old IBM eServer 325
that I could use for this purpose.
Installing and compiling a SMP kernel worked flawlessly however there is one major bug:
The machine has two bge cards bge0 and bge1 the latter works fine but the first

Mmm, are two bge same?
Have you tried polling?
try setting hw.bge0.tx_coal_ticks to 400 without polling enabled.
Default value may be too big for certain bge chips.

Little bit of a delay here ...
I will try your suggestions and reply back mid next week.

I recently installed 2.2.1 on a Dell Precision 490. It has one bge0 nic. It
works fine with the GENERIC UP kernel. When I rebooted into an SMP kernel that
I built, though, I started getting the watchdog timeout errors. I found this
report and set hw.bge0.tx_coal_ticks to 400 in sysctl.conf, but that didn't
change anything.

Anything else I can test? The NIC in question:

bge0@pci11:0:0: class=0x020000 card=0x01c11028 chip=0x160014e4 rev=0x02 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM5752 NetXtreme BCM5752 Gigabit Ethernet PCI Express'
class = network
subclass = ethernet

Did you have APIC_IO in your kernel configure?
If "yes", then try removing APIC_IO and try again.

Yes, rebuilding the SMP kernel without APIC_IO seems to have done it. Thanks.
