CardBus panics

[Josef Grosch]

I have an IBM T22 thinkpad running FreeBSD 5.4-RELEASE-p8. I have the
CardBus devices in the current kernel. When I insert a CardBus device, A
Xircom RealPort CardBus Ethernet I get a kernel panic like so;
    
Dec  9 18:42:32 paris kernel: cbb alloc res fail
Dec  9 18:42:32 paris kernel: cardbus1: Can't get memory for IO ports
Dec  9 18:42:32 paris kernel: dc0: <Xircom X3201 10/100BaseTX> port 0-0x7f mem \
0x88000000-0x880007ff,0x88000800-0x88000fff at device 0.0 on cardbus1
Dec  9 18:42:32 paris kernel: cbb alloc res fail
Dec  9 18:42:32 paris kernel: dc0: couldn't map ports/memory
Dec  9 18:42:32 paris kernel:
Dec  9 18:42:32 paris kernel:
Dec  9 18:42:32 paris kernel: Fatal trap 12: page fault while in kernel mode
Dec  9 18:42:32 paris kernel: fault virtual address     = 0x30
Dec  9 18:42:32 paris kernel: fault code                = supervisor write, pag\
e not present
Dec  9 18:42:32 paris kernel: instruction pointer       = 0x8:0xc07b01f2
Dec  9 18:42:32 paris kernel: stack pointer             = 0x10:0xd5428c10
Dec  9 18:42:32 paris kernel: frame pointer             = 0x10:0xd5428c14
Dec  9 18:42:32 paris kernel: code segment              = base 0x0, limit 0xfff\
ff, type 0x1b
Dec  9 18:42:32 paris kernel: = DPL 0, pres 1, def32 1, gran 1
Dec  9 18:42:32 paris kernel: processor eflags  = interrupt enabled, resume, IO\
PL = 0
Dec  9 18:42:32 paris kernel: current process           = 38 (cbb1)
Dec  9 18:42:32 paris kernel: trap number               = 12
Dec  9 18:42:32 paris kernel: panic: page fault
Dec  9 18:42:32 paris kernel: Uptime: 35s
Dec  9 18:42:32 paris kernel: Cannot dump. No dump device defined.
Dec  9 18:42:32 paris kernel: Automatic reboot in 15 seconds - press a key on t\
he console to abort


Any ideas How I can fix this? The suggested sysctl,
hw.pci.allow_unsupported_io_range, does not seem to exist in the kernel.
