Intermittent errors with orinoco

[dids]

Using Suse8 ( and 7.3) I have my orinoco dropping out every now and then, 
usually around every 10 mins or so
2.4.18-SMP

this is the sort of error that Im getting


May  9 13:49:23 pooter kernel: eth0: Error -16 transmitting packet
May  9 13:49:23 pooter kernel: hermes @ 0x100: CMD register busy in 
hermes_issue_command().
May  9 13:49:23 pooter kernel: eth0: Error -16 transmitting packet
May  9 13:49:23 pooter kernel: NETDEV WATCHDOG: eth0: transmit timed out
May  9 13:49:23 pooter kernel: eth0: Tx timeout! Resetting card.
May  9 13:49:23 pooter kernel: hermes @ 0x100: CMD register busy in 
hermes_issue_command().
May  9 13:49:23 pooter kernel: hermes @ 0x100: Frame allocation command failed 
(0xFFFFFFF0).
May  9 13:49:23 pooter kernel: eth0: Error -16 resetting card on Tx timeout!
May  9 13:49:27 pooter kernel: NETDEV WATCHDOG: eth0: transmit timed out
May  9 13:49:27 pooter kernel: eth0: Tx timeout! Resetting card.

It happens usually when Im playing MP3's from my server and browsing the net 
at the same time.

If I use the wavelan.com drivers I dont get this problem but I am trying to 
stick closely to Suse8.0 out of the box this time.

Does anyone know what is likely to be causing this ??
