with kernel 2.6.37.1 from Kernel:/stable/openSUSE_11.3 suspend fails on
my HP 2510p.

dmesg output is:

tpm_tis 00:02: Operation Timed out
legacy_suspend(): pnp_bus_suspend+0x0/0xa0 returns -62
PM: Device 00:02 failed to suspend: error -62
PM: Some devices failed to suspend

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?

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
