Hi Jarkko,
I tested new kernel (4.2) and it didn't help. Same problem on suspend.
Then I found another solution - boot with the "tpm_tis.interrupts=0"
kernel parameter and this resolved the issue. Could you explain me
what exactly does it make so it solves most of the problems with tpm
and suspend?
Regards

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)
done.

[ 197.512057] PM: Device 00:08 failed to suspend: error -62
[ 197.512058] PM: Some devices failed to suspend
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.
