System : OpenBSD 3.8
Architecture: OpenBSD.sparc64
Machine : sparc64
> Description:
3Com 3c905 (xl) card on my sparc64 sometimes gets stuck under
pretty modest traffic (100KB). No traffic seems to be sent or
received in this condition. At this stage the card can
be unlocked by doing 'ifconfig xl0 down' then 'ifconfig xl0 up'.
Last time for a change I tried to do 'ifconfig xl0 up' directly
without bringing the interface down first. This caused a kernel
panic as recorded below. Dmesg follows.
The machine is used as a NAT/router with hme0 facing outside and
xl0 inside a local network. The traffic that causes a lockup
is a bunch of passthrough NATed/RDRed TCP connections.
I can try 3.9-beta snapshots if this is likely to make
a difference.
