Public bug reported:
Since 10.04, my laptop does not suspend properly with tpm_infineon
tpm_bios and tpm modules present and loaded.
If I remove them, it works just right :)
Here's a snip from dmesg:
[ 941.274079] tpm_inf_pnp 00:02: saving TPM state
[ 941.294367] tpm_inf_pnp 00:02: Timeout while clearing FIFO

[ 941.294382] PM: Device 00:02 failed to suspend: error -5
