problem with using 6 wm0 devices?!
I built a set of six firewall/routers using supermicro 2U cases ( using X6DH8
each with 2 onboard i82546GB nics and one pci-x card with two additional
i82546GB. When I added
an additional 2 port card to one of the routers, the new nics attached as wm0
I can configure wm1-wm5 up with no problems, but wm0 hangs the systems. (
console responds to CR, but ifconfig doesn't return -- system is otherwise
unresponsive ) This fails with the GENERIC and install kernels for 4.0.
Looking through the archives, I thought it might be an issue with kernel
buffers, so I increased
NMBCLUSTERS to 32K, but this had no effect. I also tried netbsd 4.0 AMD64, but
that didn't work either.
A GENERIC ACPI INSTALL netbsd i386 -current kernel works fine ( as does
opensuse 10.3 ), so I think the hardware is ok, but I also tried different
cards just to be doubly sure.
I can't in good conscience use -current on a production router which is under a
load, so I looked at the diffs for sys/dev/pci/if_wm.c between
netbsd-4-0-RELEASE and -current
and to my only somewhat clueful eyes, it looks like most of the changes are
more cleanup/abstraction related rather than changes to the logic itself.
I'd appreciate any suggestions. I'm probably missing something obvious.
