Panic resource_list_alloc 7.2 stable

[Robert]

Greetings

This problem seems the same as this one from May of this year

http://lists.freebsd.org/pipermail/freebsd-stable/2009-May/050088.html

This happens on an older HP laptop. It was running on 7.1 prerelease
fine and then I updated to 7.2 Stable yesterday.

The bits from pciconf

atapci0 at pci0:0:7:1:     class=0x010180 card=0x00000000 chip=0x71118086

The date of ata-chipset.c

-rw-r--r--  1 root  wheel  188823 May 22 02:21 ata-chipset.c

The chipset is found in the above file

ata_intel_ident(device_t dev)
{
    struct ata_pci_controller *ctlr = device_get_softc(dev);
    static struct ata_chip_id ids[] =
    {{ ATA_I82371FB,     0,    0, 2, ATA_WDMA2, "PIIX" },
     { ATA_I82371SB,     0,    0, 2, ATA_WDMA2, "PIIX3" },
     { ATA_I82371AB,     0,    0, 2, ATA_UDMA2, "PIIX4" },   
            ^^^^^^^ 
     { ATA_I82443MX,     0,    0, 2, ATA_UDMA2, "PIIX4" },

I can include the dump if needed but I am not at this time to shorten
the email. But here is the panic.

Any help would be greatly appreciated.
