I gave the kernel of the day (2.6.37-rc2-1.99.2.facd623-default) a spin on an up-to-date openSUSE 11.3 system and everything works like a charm, except for one thing -- suspend to RAM (or disk for that matter).
Digging into this a bit, I found that it seems to be tpm modules that cause this, and after unloading them suspend works again:
# lsmod | grep tpm tpm_tis 12002 0 tpm 17401 1 tpm_tis tpm_bios 6748 1 tpm # rmmod tpm_tis # rmmod tpm # rmmod tpm_bios # lsmod | grep tpm #
Does it make sense to file a Bugzilla for such a case, or will that be an immediate INVALID or WONTFIX?
Actually, I am seeing exactly that as well on my x200s after putting 2.6.37-rc2 there. I am adding Rafael to CC in case it rings any bell immediately. If not, it's definitely worth upstream bugreport. Thanks.
What kind of information in addition to the above and the relevant snippet of dmesg below would be helpful in case?
