This message describes problems with two pcmcia cards. One is a 3com cardbus 10/100 (3c575), the other is a Xircom pccard CEM33 (10bt ethernet+modem 33.6). These cards are being used with an NEC Versa LX laptop.
The 3com card works ok except when ftping a file (of say, 184mb) the system freezes and there are messages on the console. They are
eth0: Host error, FIFO diagnostic register 0000. This message repeats 21 times eth0: Too much work in interrupt, status 8003. Temporarily disabling functions (7ffc).
At that point, the system is completely unusable. If the card is ejected, the kernel oops's and the system is still unusable. Note that the error messages for the oops are unavailable, since it was very long and difficult to capture.
The Xircom card freezes the system. No messages are printed. When ejecting the card, the display shifts. Column 1 starts in the middle of the screen. The system is completely unusable after inserting the card.
Before upgrading to pcmcia 3.1.5, version 3.1.1 was installed. The 3com card has experienced problems with both versions. The Xircom adapter worked under the 3.1.1 version, but not 3.1.5.
