dmesg output is:

after unloading the tpm modules (tpm_tis,tpm_infineon and tpm) the problem is gone. With kernel 2.6.37 suspend works without problems.
Is there any fix available?
Does using
itpm=1
parameter when modrpobing 'tpm' module fix the problem you are seeing?
Hi,
tpm doesn't load with this parameter
tpm: Unknown parameter `itpm'
did you mean the tpm_tis module?
Yup, sorry for the confusion.
tpm_tis 00:02: 1.2 TPM (device-id 0xB, rev-id 16) tpm_tis 00:02: Intel iTPM workaround enabled
Loaded with this parameter suspend still fails, only the error number is different
legacy_suspend(): pnp_bus_suspend+0x0/0xa0 returns 28 PM: Device 00:02 failed to suspend: error 28 PM: Some devices failed to suspend
