I apologize. I see that I'm conflating issues. I reinstalled Ubuntu
10.10, again, which has a 2.6.35 kernel. This fixes the rebooting

I've noticed a couple things.
First, I've never gotten scrambled filesystems since getting rid of
fakeraid. I'm going to blame that scrambling on that, and forget about it.
Second, I finally notice, in the ata error below, that ata3 can't be my
SSD. From a message to this list that I just found, I see that it would
be strongly suspected that I have power problems. I have an 800W power
supply, so I don't think it's not giving ENOUGH power, but the quality
might be bad? (I did a lot of damage to an old dual Athlon computer by
having an underspec'ed PS; I didn't make that mistake on this one.) I've
installed lm-sensors and will try to track this.
So I just want to dial into the reboot problem, as I reboot into Windows
(to play games) a lot. That one's pretty clear. If I upgrade to a
post-2.6.35 kernel, I get the problem, whether I'm using an SSD or a
regular HDD. Is there anything that can be done?
You can try the kernel parameter "reboot=(reboot mode)" to try and make
the system reboot in different ways:
warm Don't set the cold reboot flag
cold Set the cold reboot flag
bios Reboot by jumping through the BIOS (only for X86_32)
smp Reboot by executing reset on BSP or other CPU (only for X86_32)
triple Force a triple fault (init)
kbd Use the keyboard controller. cold reset (default)
acpi Use the RESET_REG in the FADT
efi Use efi reset_system runtime service
pci Use the so-called "PCI reset register", CF9
force Avoid anything that could hang.
If a non-default mode works better, then you should send a report to
linux-kernel about it. Contrary to the list above, I think acpi is the
default at this point.
