Re: RELENG_7 and HEAD: bge causes system hang

Good time of the day, Jung-uk Kim!

Thank you for good news!

I've just tried fresh revision of sys/dev/pci/pci.c you pointed me to
and it solved the problem for me. Actually, now I can state that there
is no problem "bge causes system hang" on RELENG_7 with bge driver (on
HP machine with Broadcom Netlink Gigabit Ethernet, chipset BCM5787).

There are several excerpts below(I think you may be interested in):

------------
# dmesg

So, great work :o).
Thank you.
