- New config options (VMSPLIT_*) to permit non-standard user/kernel
splitting on x86. Needs testing please.
- Lots of updates to the USB, PCI, driver and I2C trees. This is usually a
worry.
- Multiblock allocation speedup for ext3. This is only used by direct-IO at
present.

- If you hit a bug in -mm and it's not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt
But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.
I'm not sure if this is new to -mm3, but it's the first time I have seen it.
The sequence of events leading up to this was to reboot the machine, it came up
and crashed:

There's some trace missing here. I assume it's the same ata_device_add()
thing.
Correct. I included it to suggest a possible link with the other ATA problems I
am having and to show it's a separate report.
The important bit in this report was the SATA timing out - which it should not
be doing. There are three disks all hooked up and (most of the time) working.
Box is locked in a cabinet so it's not like any hardware had mysteriously come
loose or been bumped.

USB lost its interrupt. Could be USB, more likely ACPI.

Looks like RAID0 keeled over.
md0 is the root partition, I assume because the SATA crapped out the box was
unable to assemble the raid arrays, find root on md0 and so it panic'd.
