Some more information proving TPM is causing suspend to ram and suspend to disk
to fail. I have never used TPM, thus I can say that my laptop's TPM module is
virgin.
$ uname -a
Linux 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10
+0100 i686 i686 i386 GNU/Linux
Excerpt from /var/log/warn:
Mar 28 20:46:01 laptop kernel: [89081.781029] Freezing remaining freezable
tasks ... (elapsed 0.01 seconds) done.
Mar 28 20:46:01 laptop kernel: [89081.792110] Suspending console(s) (use

Mar 28 20:46:01 laptop kernel: [89083.816023] legacy_suspend():
pnp_bus_suspend+0x0/0x80 returns -62
Mar 28 20:46:01 laptop kernel: [89083.816026] PM: Device 00:0a failed to
suspend: error -62
Mar 28 20:46:01 laptop kernel: [89083.816028] PM: Some devices failed to
suspend
Mar 28 20:46:01 laptop kernel: [89085.064683] Restarting tasks ... done.
Workaround:
# rmmod tpm_tis
# rmmod tpm
Then suspend to ram and suspend to disk start to work.
