boot ok,but reboot hang, from 2.6.10 to 2.6.14

boot ok,but reboot hang, from 2.6.10 to 2.6.14

[Boxer Gnome]

when I reboot from linux(not from windows or BIOS,they all reboot ok
from them),it will hang after the system POST before enter the grub
menu list

This only happens in reboot from linux kernel within 2.6.10-2.6.14.




I tested the older kernel version from 2.6.8 to 2.6.14,and 2.4.31 .I
found the 2.6.8 and the 2.6.9,2.4.31 worked well without above
reboot_from_linux_with_hang_after_POST,and the 2.6.10-2.6.14 all have
this.

Did this belong to the special reboot_ fixed option  in the kernel?

I send to the LKML before ,but it seemed like  none fixed it

Can you try to pinpoint when it started happening more closely?

The differences between 2.6.9 and 2.6.10 are pretty big, and it would be 
much better if you can pinpoint it to a smaller range.

You can find three "release candidates" for 2.6.10 in

	http://www.kernel.org/pub/linux/kernel/v2.6/testing

and if you first test 2.6.10-rc2, and then depending on whether that 
already has the bug or not, you'd test 2.6.10-rc1 or 2.6.10-rc2. That 
would help pinpoint the difference to between two particular -rc kernels, 
which would be much better.

After that, I might end up still asking you to test one or two daily 
snapshots, but it may be that pinpointing when your reboot troubles 
started to just the -rc kernel might be good enough.

I tested the 2.6.10-rc1 and 2.6.10-rc2,the 2.6.10-rc1 rebooted ok,but
the 2.6.10-rc2 has that problem.

Then I test the snapshot
2.6.10-rc2-bk1,2.6.10-rc2-bk4,2.6.10-rc2-bk8,they all have this reboot
hang.

SO,I think the 2.6.10-rc1 is the last worked ok version.



Thanks

Thanks. So it's between 2.6.10-rc1 and -rc2. Good. However:

Actually, you should test 2.6.10-rc1-bk*, not -rc2-bk*.

The "-bkxxx" kernels are not release-candidates, so they are not "before" 
the real release. They are nightly snapshots _after_ the release, so 
2.6.10-rc2-bk1 is the first snapshot after 2.6.10-rc2.

So you'd be interested in the ones after -rc1, but before -rc2.

OK,I'd tested the 2.6.10-rc1-bk1,2.6.10-rc1-bk6,2.6.10-rc1-bk12,I
found the 2.6.10-rc1-bk1, 2.6.10-rc1-bk6  rebooted ok,but the
2.6.10-rc1-bk12 has that problem.


Then I tested the 2.6.10-rc1-bk8,2.6.10-rc1-bk9,2.6.10-rc1-bk10.

The 2.6.10-rc1-rc8 was still ok.the 2.6.10-rc1-bk9 began has the
reboot_hang_after_POST.

Hope this help you.

Thanks

Sorry,I typed a little error.

the"The 2.6.10-rc1-rc8 was still ok" should is "The 2.6.10-rc1-bk8 was still ok"

Ok, thanks, you've been a hero.

This cuts the changes down quite significantly. The shortlog between 
rc1-bk8 and rc1-bk9 is (if I did everything right - since that's from the 
BK days and I obviously don't have BK installed anywhere, I had to convert 
things into git to make sense of it) appended.

I _suspect_ it's the IDE changes: perhaps the fact that we enable IDE 
"stroke" by default now, which unclips the IDE disk. Maybe the BIOS is 
unhappy with that.

In your "dmesg" for a modern kernel, do you get a message like

	...: Host Protected Area detected.
		current capacity is .. sectors (.. MB)
		native  capacity is .. sectors (.. MB)

if so, that's probably it, and you could try this patch.

If that doesn't help, I can help you bisect the problem down to a smaller 
patch, if you're willing to try some patches I'd send by email?
