>Description:
When an IBM 760EL laptop is booted with a Xircom CE3 PCMCIA Ethernet adapter installed, it panics with a Fatal Trap 12 immediately after the 'CE2-10 [2.1/08342353-011295] matched "Xircom" ("CreditCard 10Base-T") [(null)] [(null)]'

When replaced with a Xircom CE3 10/100 adapter the system works fine.

The panic reads:
Fatal Trap 12: page fault while in kernel mode
fault virtual address   = 0x0
fault code              = supervisor read, page not present
intruction pointer      = 0x8:0xc0143781
stack pointer           = 0x10:0xc6100bd0
frame pointer           = 0x10:0xc6100cf4
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 50 (pccardd)
interrupt mask          = none
trap number             = 12
panic: page fault

>How-To-Repeat:
Insert a CE2 into an IBM 760EL Laptop running 4.5-RELEASE or 4.5-STABLE
