I'm running Ubuntu natty on a X301, and this consistenly and quickly fails for me; I see this in dmesg: [ 3105.290150] PM: Entering mem sleep [ 3105.290262] Suspending console(s) (use no_console_suspend to debug) [ 3105.291236] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 3105.293304] sd 0:0:0:0: [sda] Stopping disk [ 3105.340115] tpm_tis 00:0a: tpm_transmit: tpm_send: error -5 [ 3105.340124] legacy_suspend(): pnp_bus_suspend+0x0/0xa0 returns -5 [ 3105.340130] PM: Device 00:0a failed to suspend: error -5 [ 3105.410093] PM: suspend of drv:usb dev:2-3 complete after 118.970 msecs [ 3105.413289] PM: suspend of drv:sd dev:0:0:0:0 complete after 122.059 msecs [ 3105.413357] PM: Some devices failed to suspend
once I modprobe -r tpm_tis, I can suspend / resume fine. The referenced upstream bug mentions commit 59f6fbe4291fcc078ba26ce4edf8373a7620a13a as fixing this, which is definitely in the natty kernel I'm running, so i guess it's another issue, I'll remove the upstream bug link. ** Changed in: linux Importance: Unknown => Undecided ** Changed in: linux Status: Unknown => New ** Changed in: linux Remote watch: Linux Kernel Bug Tracker #20132 => None -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/602049 Title: Suspend to RAM fails due to tpm_tis kernel module (regression) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
