FreeBSD d 6.1-STABLE-200607 FreeBSD 6.1-STABLE-200607 #6: Wed Jul 26 08:21:18 UTC 2006     root at d:/usr/obj/usr/src/sys/A  amd64
Using Dell Poweredge 1950 with 2 dual-core Xeon (Id = 0xf64)
It has a mpt0: <LSILogic SAS Adapter>, and it probes with 6.1-STABLE.
It has also got 2 Broadcom NetXtreme II BCM5708C 1000Base-T (B1)
Bus: bce0: ASIC ID 0x57081010; Revision (B1); PCI-X 64-bit 133MHz
I am using the 0.9.6 version with the 1.6 2006/07/20 revision of the driver.
(Have also used the 0.9.5 driver with revision)

If using a kernel with built-in bce, it locks up when booting. (Both versions.)

If using a kernel with no built-in bce, it locks up for some while
after loading the module. (Only tested with 0.9.6.)
Then seems to work normally.
When rebooting, with 2 bces it locks up after printing system uptime.

Problem is not appearing when booted with no APIC (and no SMP).

Use bce with SMP.
