>Description:

Set up: this is a HP 712/60 with 32MB RAM. It is a diskless setup with
root swap and usr as exports to the machine. Due to current keyboard problems it is only used to log in via ssh.

after several hours of uptime with low usage the machine started to 
print the following to the console,:

iee0: iee_intr: receive ring buffer overrun
receive error rfd status: 0x0000 rfd count: 0x0000

repeated over and over together with another status count that was increasing, but I failed to copy verbatimly from the screen. Parallel the machine became unreachable over the network, it did no longer respond to ping, xterms hung, etc.
>How-To-Repeat:

1- as said in "Full Description"

2- driving high utilisation e.g. start compiling a kernel or a package the machine will be unreachable over the network after about 10 to 15min. These lock-ups though did not print to the console, as above. In these ocasions the network "just" hung.
>Fix:
