After 8.1-RELEASE was running fine, upgrading to 8.2-RELEASE caused to
stalls completely without crash during boot. I now went for a fresh
-CURRENT which still stalls/freezes completely without crashing with
last messages (captured via firewire/dcons):
atapci0: <Intel ICH8M UDMA100 controller> port

My MacbookPro4,1 is using (S)ATA controller chipset :
atapci0@pci0:0:31:1: class=0x01018f card=0x00a3106b
chip=0x28508086 rev=0x04 hdr=0x00
vendor = 'Intel Corporation'
device = '82801H (ICH8 Family) Ultra ATA Storage Controllers'
class = mass storage
subclass = ATA
atapci1@pci0:0:31:2: class=0x01018f card=0x00a3106b
chip=0x28288086 rev=0x04 hdr=0x00
vendor = 'Intel Corporation'
device = '82801 (ICH8M) 3 port SATA Controller'
class = mass storage
subclass = ATA
The issue seem to be introduced in r214016 which is a fairly large
commit about 'Set of legacy mode SATA enchancements'.
If using the tree sys/dev/ata@214015 it boots fine:
# svn up -r214015 /usr/src-head/sys/dev/ata
# make -C /usr/src-head buildkernel installkernel
And the next commit (which affects my chipset as well) it stops working:
# svn up -r214016 /usr/src-head/sys/dev/ata
# make -C /usr/src-head buildkernel installkernel
Does anybody has the same SATA controller chipset (ATA_I82801HBM_S1),
and is able to boot fine?
Any hints on how to debug this issue much appreciated as I having
quite some trouble understanding what the patch changed and how-to
debug this, as it completely freezes the machine, making it impossible
to get into the debugger.
