This is strange because the driver mainly was changed from cli/sti to
spinlocks.

There are already a lot of printk's in the code, you just have to set
vortex_debug to a higher value.

Set_rx_mode should be called only once from vortex_open AFAIK. It is also
called from vortex_error (so this can happen an unlimited number of
times) on HostError handling; however, just before this there is an error
message that should appear: 'Host error: FIFO diagnostic register...'
which is not mentioned by you. Does this message appear?

Yes, it's working for me on Intel SMP. However, I also have some
hard-to-reproduce locks which seem to appear after more than 24h of
continuous high load.

AFAIK, spinlocks should work the same on different HW architectures; as
they work for me and Andrew, I seriously doubt that they are guilty.

I would like to see the messages produced by the driver with a higher
vortex_debug value (f.e. 5); the existing printk's offer good info about
what is going on. To get them on the console you should have:
kern.*		/dev/console
in your /etc/syslog.conf file.
