           Summary: 3c59x.c: 3c556B Laptop Hurricane not correctly
                    detected/run
    Kernel Version: 2.5.66
            Status: NEW
          Severity: normal
             Owner: jgarzik@pobox.com
         Submitter: brassmold@yahoo.com


Distribution: Redhat 9 with module-init-tools 2.4.21-18
Hardware Environment: IBM Thinkpad T21 type 2647-5BU
Software Environment: kernel 2.5.66 (stock)
Problem Description: The laptop's integrated ethernet chipset, a 
3Com PCI 3c556B Laptop Hurricane (according to a 2.4.20 Redhat 9 kernel) does
not correctly detect under kernel 2.5.66 and as a result does not work
correctly. A DHCP fails with event errors.

Steps to reproduce:
Attempt to modprobe the card. In a successful 2.4.20 modprobe (debug=2), you see:
PCI: Found IRQ 11 for device 00:03.0
PCI: Sharing IRQ 11 with 00:03.1
PCI: Sharing IRQ 11 with 08:02.0
PCI: Sharing IRQ 11 with 08:02.1
