[SOLVED] New kernel, no complete shutdown

black-clover · 02-18-2019, 07:15 PM

Hi,

I have compiled a new, slimmed down kernel 4.9.144 on my Debian testing box on a Compaq laptop.
Everything seems to work fine so far except when the system shuts down, it does everything fine but does not turn the laptop off at the end of the process.
I have to do that manually.

The only error message I get on dmesg is:

Code:

[    0.255328] PnPBIOS: PnP BIOS version 1.0, entry 0xf0000:0xb197, dseg 0x400
[    0.255408] PNPBIOS fault.. attempting recovery.
[    0.255479] PnPBIOS: Warning! Your PnP BIOS caused a fatal error. Attempting to continue
[    0.255571] PnPBIOS: You may need to reboot with the "pnpbios=off" option to operate stably
[    0.255664] PnPBIOS: Check with your vendor for an updated BIOS
[    0.255738] PnPBIOS: dev_node_info: unexpected status 0x24
[    0.255809] PnPBIOS: Unable to get node info.  Aborting.

which I don't know if it's related.

If someone wishes to take a look at the kernel config file, it can be found at:

Thanks.

Hi:

Until you find a fix for the shutdown issue you can run this as root rather than a hard shutdown.

Code:

sudo shutdown -h now

I'm not sure if the output from dmesg is related or not either and I wouldn't set "pnpbios=off" in the BIOS w/o knowing what exactly that will do.

Here's an article that explains setting the "pnpbios=off".

Hello Ztcoracat,

thanks for the suggestion.
Unfortunately, even with

Code:

sudo shutdown -h now

At the end of the shutdown process it simply hangs and says system halted but the machine does not shut off.
Last message is:

Code:

reboot: system halted

I hate to guess, but I would guess it is the bios that actually shuts down the hardware. The operating system just passes that message to the bios, and if you have an issue as above "pnpbios" thingy, that could be the cause of it.

perhaps your kernel is misconfigured and does not pass the message correctly. I don't know exactly what pnpbios is, but it sounds like plug'n'play bios, without that explaining it.

I have experienced the issue you describe before, but without that specific error. And it is frustrating yes. I think in my case it was due to some acpi issues. But that might perhaps be up the same lane as your issue.

I don't want to say you should pass "pnpbios=off" to your kernel at boot without knowing what that is and means. I would first reconfigure the kernel and look into any "pnpbios" entries there and what it does exactly. Perhaps you added it to the Kernel built in? Perhaps it should not be?

According to this, pnpbios is obsolete. Acpi is supposed to replace it.

There's a kernel option called PNPACPI which might be relevant. You could check what it does in your build menu.

I have to agree with zeebra in regard to the kernel.

If the new kernel that you compiled wasn't done correctly or the proper modules added it could be misconfigured.

This is a good guide for compiling and installing the Linux kernel.

I went through the kernel options I had disabled and off course among them was the power control driver.
Changed that and recompiled and now the machine shuts off just fine.

Thanks everyone for the feedback.

You're Welcome-
Glad to hear your machine shuts down now.
