None 3c589 3cxem556b FIFO diagnostic register 2011 

Forum: 3Com PCMCIA Ethernet Adapter Issues
Date: 1999, Nov 24
From: Andy Evans andye

RedHat 6.1 modified with latest kernel and pcmcia-cs

Linux PCMCIA Card Services 3.1.4 kernel build: 2.2.13 #2 Tue Nov 23 10:38:32 EST 1999

options: [pci] [apm] [pnp]

detection on boot and insertion/removal seems fine

I cannot seem to get the card to transfer large amounts of data without interrupts being lost. Any guidance or suggestions will be welcome. I have attempted usual fixes; scan_io=0, fast_pci, cmd_time, etc. There is a "odd IO request" error.

Thanks in advance,
