I believe the change that broke things is introduction of
pci_fixup_parent_subordinate_busnr().
The patch here does two things:
- hunk #1 should fix the problems you've seen when you boot without
additional "pci" kernel options;
- hunk #2 supposedly fixes boot with "pci=assign-busses" option which
otherwise hangs Acer TM81xx machines as reported.
Please try this with and without "pci=assign-busses". If it boots,
I'd like to see 'lspci -vvx' for both cases.

since we otherwise get into a lock reversal deadlock if a read locked
runlist is passed in. In the process also change it to take an ntfs
inode instead of a vfs inode as parameter.

While this is true, E8390_CMD is zero on i386, and thus there should be no
effect for these machines. Machines like Mac, Amiga etc. which use Alan's
clever register mapping may have a non-zero E8390_CMD and result in bogus
"transmitter busy" type messages from this bug.
Fixes BUG# 3991.

Fix to allow SCTP_SHUTDOWN notifications to be received on 1-1 style
SCTP SOCK_STREAM sockets.
Add SCTP_SHUTDOWN notification to the receive queue before updating
the state of the association.

This patch fixes a number of bugs. It cannot be reasonably split up in
multiple fixes, since all bugs interact with each other and affect the same
function:
Bug #1:
The event cache code cannot be called while a lock is held. Therefore, the
call to ip_conntrack_event_cache() within ip_ct_refresh_acct() needs to be
moved outside of the locked section. This fixes a number of 2.6.14-rcX
oops and deadlock reports.
Bug #2:
We used to call ct_add_counters() for unconfirmed connections without
holding a lock. Since the add operations are not atomic, we could race
with another CPU.
Bug #3:
ip_ct_refresh_acct() lost REFRESH events in some cases where refresh
(and the corresponding event) are desired, but no accounting shall be
performed. Both, evenst and accounting implicitly depended on the skb
parameter bein non-null. We now re-introduce a non-accounting
"ip_ct_refresh()" variant to explicitly state the desired behaviour.

As noted by Alexey Dobriyan, the DEBUGP statement prints the wrong
callID.

Since the introduction of TSO pcount a year ago, it has been possible
for tcp_fragment() to cause packets_out to decrease. Prior to that,
tcp_retrans_try_collapse() was the only way for that to happen on the
retransmission path.
When this happens with Reno, it is possible for sasked_out to become
invalid because it is only an estimate and not tied to any particular
packet on the retransmission queue.
Therefore we need to adjust sacked_out as well as left_out in the Reno
case. The following patch does exactly that.
This bug is pretty difficult to trigger in practice though since you
need a SACKless peer with a retransmission that occurs just as the
cached MTU value expires.
