for all following kernels I installed, same thing happens. kernel-2.6.18-128.el5 kernel-2.6.18-157.el5 kernel-2.6.18-141.el5
This sounds more like a kernel issue than a cpuspeed package issue.
...the heck? I swear I said "kernel", not "kdepim"... fixing...
>1.echo disk > /sys/power/state >2.resume the machine Kexin, what did you do to resume the machine? Thanks, P.
click on the "reboot" button on the http://lab.rhts.bos.redhat.com/cgi-bin/rhts/system.cgi?id=1112 it is through power switch?
(In reply to comment #6) > click on the "reboot" button on the > http://lab.rhts.bos.redhat.com/cgi-bin/rhts/system.cgi?id=1112 > it is through power switch? Yes, I always thought that did a hard rest of the system. I'll ask in #rhts ... P.
Kexin, The sequence is: 1. use console to access system console 2. [root@hp-dl580g5-01 sys]# find ./ -name *cpufreq* > /tmp/before [root@hp-dl580g5-01 sys]# cat /tmp/before ./module/cpufreq_ondemand ./module/acpi_cpufreq ./module/cpufreq ./devices/system/cpu/cpu15/cpufreq ./devices/system/cpu/cpu14/cpufreq ./devices/system/cpu/cpu13/cpufreq ./devices/system/cpu/cpu12/cpufreq ./devices/system/cpu/cpu11/cpufreq ./devices/system/cpu/cpu10/cpufreq ./devices/system/cpu/cpu9/cpufreq ./devices/system/cpu/cpu8/cpufreq ./devices/system/cpu/cpu7/cpufreq ./devices/system/cpu/cpu6/cpufreq ./devices/system/cpu/cpu5/cpufreq ./devices/system/cpu/cpu4/cpufreq ./devices/system/cpu/cpu3/cpufreq ./devices/system/cpu/cpu2/cpufreq ./devices/system/cpu/cpu1/cpufreq ./devices/system/cpu/cpu0/cpufreq 3. echo disk > /sys/power/state 4. let system go to sleep 5. resume by pressing a few keys on the system console 6. [root@hp-dl580g5-01 sys]# find ./ -name *cpufreq* ./module/cpufreq_ondemand ./module/acpi_cpufreq ./module/cpufreq ./devices/system/cpu/cpu12/cpufreq ./devices/system/cpu/cpu8/cpufreq ./devices/system/cpu/cpu4/cpufreq ./devices/system/cpu/cpu3/cpufreq ./devices/system/cpu/cpu2/cpufreq ./devices/system/cpu/cpu1/cpufreq ./devices/system/cpu/cpu0/cpufreq I'll have to put some code in to determine why the files didn't "return" after the resume. P.
Actually, it doesn't look like the system is entering suspend at all: CPU6 is down CPU 7 is now offline CPU7 is down CPU 8 is now offline CPU8 is down CPU 9 is now offline CPU9 is down CPU 10 is now offline CPU10 is down CPU 11 is now offline CPU11 is down CPU 12 is now offline CPU12 is down Breaking affinity for irq 59 CPU 13 is now offline CPU13 is down Breaking affinity for irq 14 CPU 14 is now offline CPU14 is down Breaking affinity for irq 75 CPU 15 is now offline CPU15 is down Stopping tasks: ====================================================================== stopping tasks timed out after 20 seconds (1 tasks remaining): cciss_scan00 Restarting tasks...<6> Strange, cciss_scan00 not stopped done Enabling non-boot CPUs ... Initializing CPU#1 Intel(R) Xeon(R) CPU E7340 @ 2.40GHz stepping 0b CPU1 is up P.
Suspend works in -128.el5 (RHEL5.3 kernel). I'm going to do a bit of debugging to figure out why the cciss_scan00 thread isn't stopping. P.
Opened 513472 to track the cciss issue. Now back to this bug -- it looks like the missing sysfs file problem occurs in 5.3 (128.el5) as well. Therefore not a regression or a blocker, but still needs to be fixed. I'm going to push this to 5.5. P.
This seems to hit quite a few systems so it is not specific to this system. Raising the priority and severity. What is odd is that the first physical package seems to be working properly (cpus 0,4,8,12) and the other packages' first cpu are working properly (1,2,3). Maybe a race of some sort... looking into it now. P.
Here's what the issue is and it is a race in the code. During regular boot-up all the cpus are online. But during a resume, they are not. There's a check in the code to determine if the cpus are online, and if they are offline we do not repopulate part of the cpufreq sysfs. Offending codepath is drivers/cpufreq/cpufreq.c: line 806 /* symlink affected CPUs */ for_each_cpu_mask(j, policy->cpus) { if (j == cpu) continue; if (!cpu_online(j)) <----------- resume codepath bails here. continue; dprintk("CPU %u already managed, adding link\n", j); cpufreq_cpu_get(cpu); cpu_sys_dev = get_cpu_sysdev(j); sysfs_create_link(&cpu_sys_dev->kobj, &policy->kobj, "cpufreq"); } I have a few ideas on how to fix this, but first I need to see if this same issue hits upstream. AFAICT it does, but I want to be sure they haven't fixed it in some other way. P.
Dave Jones is to blame :) (joking ... just kidding around) upstream commit 8ff69732d484ea9ccbf242cc49b4fe9538e64c71 P.
Found the issue. The cpufreq code sets the per_cpu policy_cpu value when the logical cpu is offline. The code should not do this.

This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.
in kernel-2.6.18-168.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Please do NOT transition this bugzilla state to VERIFIED until our QE team has sent specific instructions indicating when to do so. However feel free to provide a comment indicating that this fix has been verified.
Did you guys have a machine that has processors with cpu frequency scaling and at the same time will resume after sleeping to disk (echo disk > /sys/power/state) I could test on?
