[2.5.44] Poweroff after warm reboot

[2.5.44] Poweroff after warm reboot

[DevilKin]

Hello,

If I reboot my laptop with kernel 2.5.44 (warm reboot), the machine reboots, 
loads the kernel, and then in the middle of the booting process powers off. 

Doing an actual shutdown (poweroff) results in a clean boot next time.

This behaviour is not present with kernel 2.5.40.

The last message I'm able to see before the screen goes blank is something 
about serial io being detected/loaded.

Is this a known bug?

PC is a Dell Latitude CPI A XT 366. More info available if needed.

Hmm... maybe it has something to do with ACPI ? Could you try booting the 
kernel after a warm reboot with ACPI disabled ?

An other thing I can think about is that a driver does odd things due to the 
fact that the hardware isn't reinitialized completely. See dmesg what driver 
comes after that serial driver and disable the serial driver and / or the 
other driver. See if this helps.

It's APM, not ACPI (luckely :oP)

Well, I'd first have to figure out what driver it is, since my screen goes 
entirely blank...

FWIW I have a very similar machine (its not in front of me
unfortunately) that used to exhibit the same behavior under Win2k.  I
haven't been using it since I got into a position to put it back under
Linux (the battery is shot - I was just using it to run software
required by my old ISP) but I can give it a try if needed.

It was exactly as described, only under windows - the machine would
reboot, bios go past, the initial boot menu would go, then partway
though the color-bar boot screen it would just turn off.

This problem is still present with 2.5.45 and 2.5.46.

<AOL>same here</AOL>

Actually I haven't tested further kernels than 2.5.45 as I just spent the night moving
 files from the laptop that suffered, alas, uncorrectable drive errors. Luckily the only
 file lost was linux-2.5.45.tar :) I only hope that the poweroffs didn't help the drive
 to die earlier than it should have :/
