And we observed big drop of suspend quality. Previously, we have run into this "e1000e Hardware Error" issue, occasionally. But now, on a NUC I have, system suspend-to-mem fails within 10 suspend cycles in most cases, but won't work again until a reboot. https://bugzilla.kernel.org/show_bug.cgi?id=205015 IMO, this is a regression, and we need to find a way to fix it. thanks, rui On Sat, 2020-05-23 at 20:20 +0800, Kai-Heng Feng wrote: > [+Cc intel-wired-lan] > > > On May 21, 2020, at 13:27, kernel test robot > > wrote: > > > > Greeting, > > > > FYI, we noticed the following commit (built with gcc-7): > > > > commit: e86e383f2854234129c66e90f84ac2c74b2b1828 ("e1000e: Warn if > > disabling ULP failed") > > https://git.kernel.org/cgit/linux/kernel/git/jkirsher/next-queue.git > > dev-queue > > kern :warn : [ 240.884667] e1000e 0000:00:19.0 eth0: Failed to > disable ULP > kern :info : [ 241.896122] asix 2-3:1.0 eth1: link up, 100Mbps, > full-duplex, lpa 0xC1E1 > kern :err : [ 242.269348] e1000e 0000:00:19.0 eth0: Hardware > Error > kern :info : [ 242.772702] e1000e 0000:00:19.0: > pci_pm_resume+0x0/0x80 returned 0 after 2985422 usecs > > So the patch does catch issues previously ignored. > > I wonder what's the next move, maybe increase the ULP timeout again? > > Kai-Heng > > > in testcase: suspend-stress > > with following parameters: > > > > mode: mem > > iterations: 10 > > > > > > > > on test machine: 4 threads Broadwell with 8G memory > > > > caused below changes (please refer to attached dmesg/kmsg for > > entire log/backtrace): > > > > > > > > > > If you fix the issue, kindly add following tag > > Reported-by: kernel test robot > > > > SUSPEND RESUME TEST STARTED > > Suspend to mem 1/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-1/10 > > -O /dev/null > > Done > > Sleep for 10 seconds > > Suspend to mem 2/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-2/10 > > -O /dev/null > > Done > > Sleep for 10 seconds > > Suspend to mem 3/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-3/10 > > -O /dev/null > > Done > > Sleep for 10 seconds > > Suspend to mem 4/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-4/10 > > -O /dev/null > > Done > > Sleep for 10 seconds > > Suspend to mem 5/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-5/10 > > -O /dev/null > > Done > > Sleep for 10 seconds > > Suspend to mem 6/10: > > /usr/bin/wget -q --timeout=1800 --tries=1 --local-encoding=UTF-8 > > http://inn:80/~lkp/cgi-bin/lkp-jobfile-append-var?job_file=/lkp/jobs/scheduled/lkp-bdw-nuc1/suspend-stress-10-mem-debian-x86_64-20180403.cgz-e86e383f2854234129c66e90f84ac2c74b2b1828-20200517-66267-13fgkna-8.yaml&job_state=suspending-6/10 > > -O /dev/null > > Failed > > > > > > > > To reproduce: > > > > git clone https://github.com/intel/lkp-tests.git > > cd lkp-tests > > bin/lkp install job.yaml # job file is attached in this > > email > > bin/lkp run job.yaml > > > > > > > > Thanks, > > Rong Chen > > > > > script.txt> > >
