Date: Sun, 1 Aug 2010 14:19:35 GMT [thread overview]
Message-ID: <bug-16489-12968@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=16489
Summary: kmemleak after suspend2ram in cpufreq driver
Product: Power Management
Version: 2.5
Kernel Version: 2.6.35-rc6+
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: cpufreq
AssignedTo: cpufreq@vger.kernel.org
ReportedBy: toralf.foerster@gmx.de
Regression: No
If I suspend2ram my ThinkPad T400 and wake it up, then
/sys/kernel/debug/kmemleak contains an entry like this:
unreferenced object 0xf6788640 (size 64):
comm "modprobe", pid 1038, jiffies 4294676277 (age 7682.155s)
hex dump (first 32 bytes):
00 00 00 00 e8 a2 24 00 01 00 00 00 00 9f 24 00 ......$.......$.
02 00 00 00 00 6a 18 00 03 00 00 00 00 35 0c 00 .....j.......5..
backtrace:

What's interesting is that this entry only appears after the wakeup (and an
additional wait time of usually 20 minutes) however the "age" is from the boot
time of that system.
