Description:
Since kernel version 3.7.1 from the testing-repository, my Thinkpad T43 fails to resume from suspend to ram. The screen remains blank, only the sleep led stops blinking and the hdd wakes up. I compiled the latest stable kernel 3.7.3 with PM_DEBUG and PM_TRACE enaled (see attached log) and tried to debug it following this documentation http://www.kernel.org/doc/Documentation/power/s2ram.txt . But in dmesg, "Magic number" appears without further information: 540 [ 0.997657] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0 541 [ 1.003574] PM: Hibernation image not present or could not be loaded. 542 [ 1.003591] registered taskstats version 1 543 [ 1.004037] Magic number: 13:859:428 544 [ 1.004129] rtc_cmos 00:06: setting system clock to 2013-01-18 11:25:17 UTC (1358508317) 545 [ 1.004267] Freeing unused kernel memory: 552k freed 546 [ 1.004586] Write protecting the kernel text: 4080k 547 [ 1.004613] Write protecting the kernel read-only data: 1248k 548 [ 1.016965] systemd-udevd[40]: starting version 197 549 [ 1.071171] ACPI: bus type usb registered Does someone knows further debugging steps? Additional info: * package version(s) pm-utils 1.4.1-5 * config and/or log files etc. Steps to reproduce: pm-suspend |

I'll check for that file after I recompiled the kernel and report here, thanks for the hint.

I ran the script mentioned here: http://www.kernel.org/doc/Documentation/power/s2ram.txt . After reboot (wakeup from suspend failed ofc), dmesg has now this interesting lines:
[ 0.995334] registered taskstats version 1
[ 0.995779] Magic number: 13:938:121
[ 0.995782] hash matches drivers/base/power/main.c:515
[ 0.995874] rtc_cmos 00:06: setting system clock to 2013-01-26 09:07:07 UTC (1359191227)
/sys/power/pm_trace_dev_match is still empty :(
I guess I should git clone in old revisions of the linux PKGBUILD of the testing repository?
Maybe the notebooks Thinkpad X60 and Samsung X20 are also affected by this regression.
I was able to check the notebooks Thinkpad R52 and T40 but both work fine using the latest stable kernel.
I attached a file with dmidecode output.
