[info] VPD scanning hangs with PV-BT878P+ TV card (Follow-up: i386 kernel just stops booting)

Hello again,

following Bruce's advice I'm sending more information about PV-BT878P+
TV card(PCI). To sum the problem up - if hw.pci.enable_vpd is set to 1
kernel stops responding in sys/dev/pci/pci.c in pci_read_extcap() (case
PCIY_VPD) [1].

Unfortunately sysutils/lspci doesn't seem to work here (neither on
RELENG_6 nor CURRENT), I used Knoppix CD for that:

root@1[~]# lspci --version
lspci version 2.1.11
root@1[~]# grep snapshot /usr/share/misc/pci.ids
# Daily snapshot on Mon 2007-02-12 02:05:02


Outputs of verbose boot, 'pciconf -vl' (both 6.2-STABLE) and 'lspci -vv'
(Linux) attached. Let me know if there's anything more needed.

Cheers,

Karol
