I've added the relevant verbose boot messages from your earlier kernel below each one: > pci0: on pcib0 > pci0: pci0:0:20:2 bar 0x10 failed to allocate > pcib1: at device 1.0 on pci0 found-> vendor=0x1002, dev=0x4383, revid=0x00 domain=0, bus=0, slot=20, func=2 class=04-03-00, hdrtype=0x00, mfdev=0 cmdreg=0x0006, statreg=0x0410, cachelnsz=16 (dwords) lattimer=0x40 (1920 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) intpin=a, irq=10 powerspec 2 supports D0 D3 current D0 map[10]: type Memory, range 64, base 0xcc408000, size 14, enabled pcib0: matched entry for 0.20.INTA pcib0: slot 20 INTA hardwired to IRQ 16 > pcib4: at device 20.4 on pci0 > pcib4: failed to allocate initial memory window: 0xcc100000-0xcc1fffff > pci2: on pcib4 > pci2: pci0:2:4:0 bar 0x10 failed to allocate > cbb0: irq 20 at device 4.0 on pci2 found-> vendor=0x1180, dev=0x0476, revid=0xb6 domain=0, bus=2, slot=4, func=0 class=06-07-00, hdrtype=0x02, mfdev=1 cmdreg=0x0007, statreg=0x0210, cachelnsz=0 (dwords) lattimer=0x40 (1920 ns), mingnt=0x80 (32000 ns), maxlat=0x07 (1750 ns) intpin=a, irq=10 powerspec 2 supports D0 D1 D2 D3 current D0 map[10]: type Memory, range 32, base 0xcc100000, size 12, enabled pcib4: failed to allocate initial memory window (0xcc100000-0xcc1fffff,0x100000) pcib4: matched entry for 2.4.INTA pcib4: slot 4 INTA hardwired to IRQ 20 cbb0: irq 20 at device 4.0 on pci2 pcib0: allocated type 3 (0xcc500000-0xcc5fffff) for rid 20 of pcib4 pcib4: allocated initial memory window of 0xcc500000-0xcc5fffff pcib4: allocated memory range (0xcc500000-0xcc500fff) for rid 10 of cbb0 cbb0: Lazy allocation of 0x1000 bytes rid 0x10 type 3 at 0xcc500000 So the second case actually recovers and allocates a different range. Can you try booting with 'debug.acpi.disabled=sysres' set in the loader? Also, can you get the output of 'devinfo -rv' from a working kernel? -- John Baldwin
