i got back to looking at the landisk not working since 2.6.31. linux-3.5
boots up with better information, so we can get further in figuring out what
went wrong. for a recap, 99f95f117848088f2708b45c70be73152e78bb8a was the
last rev i could boot.
with 2.6.30.9, i see these address ranges:
Autoconfig PCI channel 0x8c3543e0
Scanning bus 00, I/O 0xfe240000:0xfe280000, Mem 0xfd000000:0xfe000000
00:00.0 Class 0200: 10ec:8139 (rev 20)
I/O at 0xfe240000 [size=0x100]
Mem at 0xfd000000 [size=0x100]
00:01.0 Class 0180: 1191:0009 (rev 07)
I/O at 0xfe240100 [size=0x8]
I/O at 0xfe240108 [size=0x4]
I/O at 0xfe240110 [size=0x8]
I/O at 0xfe240118 [size=0x4]
I/O at 0xfe240120 [size=0x10]
00:02.0 Class 0c03: 1033:0035 (rev 43)
Mem at 0xfd001000 [size=0x1000]
00:02.1 Class 0c03: 1033:0035 (rev 43)
Mem at 0xfd002000 [size=0x1000]
00:02.2 Class 0c03: 1033:00e0 (rev 04)
Mem at 0xfd003000 [size=0x100]
but with 3.5, i see:
PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [io 0x1000-0x3fffff]
pci_bus 0000:00: root bus resource [mem 0xfd000000-0xfdffffff]
pci 0000:00:01.0: BAR 6: assigned [mem 0xfd000000-0xfd00ffff pref]
pci 0000:00:02.0: BAR 0: assigned [mem 0xfd010000-0xfd010fff]
pci 0000:00:02.1: BAR 0: assigned [mem 0xfd011000-0xfd011fff]
pci 0000:00:00.0: BAR 0: assigned [io 0x1000-0x10ff]
pci 0000:00:00.0: BAR 1: assigned [mem 0xfd012000-0xfd0120ff]
pci 0000:00:02.2: BAR 0: assigned [mem 0xfd012100-0xfd0121ff]
pci 0000:00:01.0: BAR 4: assigned [io 0x1400-0x140f]
pci 0000:00:01.0: BAR 0: assigned [io 0x1410-0x1417]
pci 0000:00:01.0: BAR 2: assigned [io 0x1418-0x141f]
pci 0000:00:01.0: BAR 1: assigned [io 0x1420-0x1423]
pci 0000:00:01.0: BAR 3: assigned [io 0x1424-0x1427]
notice how the dma ranges are completely in the wrong region. any quick ideas
where to fix this ? :)
