tpm_tis driver failed to suspend, error -62

[Aaron Lu]

Hi Rajiv,

Not sure if I should send this to you, please kindly forward it to the
appropriate person if not, thanks.

Peter has encountered a problem during suspend, the tpm_tis driver's
suspend callback will fail, the relevant message is:

[ 192.281757] PM: Syncing filesystems ... done.
[ 192.692479] Freezing user space processes ... (elapsed 0.01 seconds)

And the problem has been there since v2.6.32(shipped in ubuntu 10.04),
and the latest upstream tree(v3.9-rcx) also has this problem. The bug
link is here:
https://bugzilla.kernel.org/show_bug.cgi?id=45761

Please feel free to ask for more information, thanks.

Error 62 is ETIME. The driver is timing out during a tpm_send,
possibly trying to send the Tpm_SaveState command.

It may be that you cannot talk to the TPM at all. Have you tried
sending messages to the TPM before suspending?

Are there any other tpm entries in the syslog? Like at boot?

What model TPM is it?

Hi! Sadly, I have to say that I'm totally oblivious to power-related
stuff both in software and hardware, so I have no idea what you are
asking or proposing.. :)

I don't know if you have access to the files I've included in the bug
report, so here are the links to them:
https://launchpadlibrarian.net/105830773/lspci.txt
https://launchpadlibrarian.net/95994294/AcpiTables.txt
https://launchpadlibrarian.net/95994318/BootDmesg.txt
https://launchpadlibrarian.net/95994354/UdevDb.txt

Regarding the syslog during boot, is that the same as the BootDmesg
I've attached? Or should I search in another log file?
I'm not sure about the model, but I was hoping you could deduct
something from the UdevDb or the lspci output above.

BR,
Peter

[Rajiv Andrade]

Sending again, plain text.

Hey Aaron,

Sorry for the delay. Can you send us the dmesg output after setting
loglevel=7 at boot time? Additionally, can you send us the TPM
manufacturer model/version?

# cat /sys/devices/pnp0/00\:0*/caps

Adding Kent.

Cheers,
Rajiv

Hi Aaron, Rajob, PeterA and everybody else,

According to the BootDmesg.txt it's an Infineon TPM
[ 0.293936] pnp 00:0a: Plug and Play ACPI device, IDs IFX0102 PNP0c31 (active)
[ 12.413651] tpm_tis 00:0a: 1.2 TPM (device-id 0xB, rev-id 16)




@PeterA:
Can you perhaps try find out the exact tpm version?
1) Install trousers and tpm_tools (emerge app-crypt/trousers app-crypt/tpm-tools)
2) Kill the tcsd and run it in the foreground
# pkill -9 tcsd
# tcsd -f
(if it says up and running you can send it to background)
3) Run
#tpm_version and post the output.



Also the flags etc would perhaps be handy, they can be retrieved via sysfs - on you machine it _should_ be
# cat /sys/devices/pnp0/00:0a/*
and also post the output.


What also might be worth a look - in your bugzilla it states:
[ 0.225891] pnp 00:0a: Plug and Play ACPI device, IDs IFX0102 PNP0c31 (active)
[ 9.150673] tpm_tis 00:0a: 1.2 TPM (device-id 0xB, rev-id 16)
[ 9.292148] tpm_tis 00:0a: Adjusting TPM timeout parameters.

value
[ 10.084077] tpm_tis 00:0a: TPM is disabled/deactivated (0x7)


Can you perhaps try to enable your TPM in the BIOS? It's quite often hidden under "embedded security device" or "system security".
Quite often you have to have a bios password set to access these settings.
If your system does not have bios support for TPMs, please tell me so and I'll try to help you out.

Thanks,
PeterH

Hi Peter!

Thank you for your help! I'm going away for the Easter holiday, and
will be back on Monday/Tuesday. I will try to supply the information you
need at that time, since I won't be bringing my laptop with me.

I've enabled it in BIOS now, and the output seems to be a bit
different. Not too uplifting though...

Okay it seems it's not 00:0a ;/

Can you check the node in dmesg again?
You can try to find it also by
find /sys -name '*duration*'

Hi Kent

The values I'm seeing are:

root@zepto:~# cat /sys/class/misc/tpm0/device/timeouts

752000 2000000 752000 752000 [adjusted]

So I guess these are within a normal range?

Yes, these look normal. So it seems you can send commands to the TPM
up until you try to suspend? Can you try to cat other files like
/sys/class/misc/tpm0/device/pcrs? This is the simplest way to send some
command to the TPM...

To be able to do the 'cat' above, I usually need to restart my
computer, otherwise the files aren't there. That's probably after I've
put the computer in sleep mode (which works if I add tpm_tis to the
module blacklist). Perhaps the same problem is related to this one:
I just did a grep of my dmesg and saw some new error messages (28) in
it. Perhaps they started occurring after I enabled it in BIOS.

Your TPM failed its internal self test (rc=28). At this point it will
have gone shut down. Looks like your hardware is broken. :(

[Kent Yoder]

So the above messages happen at the time you reinsert the module
after a resume?

[petera...@gentoo.se]

Sadly I don't know. Reinserting the module after a resume doesn't
really seem to do much, for instance it doesn't recreate the directories
I listed/cat above.

But since one of the messages is after 4320 (seconds?) I guess it must
be something like that. But I didn't see them when I tried modprobing
the module several times, to get the directories in /sys/ back.
