https://bugzilla.novell.com/show_bug.cgi?id=335862#c1 Summary: Resume from a suspended state stalls the machine. Product: openSUSE 10.3 Version: Final Platform: i586 OS/Version: openSUSE 10.3 Status: NEW Severity: Critical Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: jjaimon@novell.com QAContact: qa@suse.de Found By: Customer I reported this issue in the linux mailing list and Andreas suggested that I file a bug report or report this in the kernel mailing list. So, doing both. Hardware: IBM T60p with 2GB memory. Using the ATI drivers and compiz enabled. I have been observing that laptop is too slow when it resumes from suspend (T61p with 2GB ram), it takes more than 10 minutes ( or never) before the system starts responding normally. There will be continuous read from the hard disk during this time. I noticed the following in my top (3 outputs taken at different times) after 5 mins-------------------------------- Cpu(s): 1.2%us, 2.0%sy, 0.0%ni, 56.7%id, 32.2%wa, 0.1%hi, 7.9%si, 0.0%st Mem: 2075132k total, 299748k used, 1775384k free, 264k buffers Swap: 2097140k total, 567580k used, 1529560k free, 26856k cached after 10 mins-------------------------------- Cpu(s): 1.3%us, 2.4%sy, 0.0%ni, 64.8%id, 26.5%wa, 0.1%hi, 4.8%si, 0.0%st Mem: 2075132k total, 256348k used, 1818784k free, 300k buffers Swap: 2097140k total, 581164k used, 1515976k free, 28740k cached after 12 mins-------------------------------- top - 19:29:29 up 17:53, 6 users, load average: 4.63, 5.56, 5.86 Tasks: 163 total, 1 running, 160 sleeping, 0 stopped, 2 zombie Cpu(s): 0.9%us, 1.5%sy, 0.0%ni, 57.8%id, 36.6%wa, 0.1%hi, 3.1%si, 0.0%st Mem: 2075132k total, 187348k used, 1887784k free, 300k buffers Swap: 2097140k total, 609680k used, 1487460k free, 18480k cached -------------------------------- It shows that I/O is very high during this period. Though I have 2GB memory, only 200-300MB is used where as 550-600MB swap is used. Why is it this way? Also, only one task is running out of 163 total tasks in the system. The kernel I have is 2.6.22.9-0.4-default #1 SMP Here is another output that I took 15 minutes after resuming. Again, RES is very low for all processes and it looks like VM is still thinking that the main memory is not available. A VM bug? I can still see my harddisk grinding continuously. top - 23:34:43 up 21:58, 6 users, load average: 3.16, 3.37, 4.73 Tasks: 165 total, 1 running, 162 sleeping, 0 stopped, 2 zombie Cpu(s): 1.4%us, 2.4%sy, 0.0%ni, 45.2%id, 44.2%wa, 0.3%hi, 6.5%si, 0.0%st Mem: 2075132k total, 467476k used, 1607656k free, 600k buffers Swap: 2097140k total, 680644k used, 1416496k free, 128576k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3081 root 15 0 564m 74m 14m S 2 3.7 43:26.70 X 4272 jjaimon 15 0 260m 68m 13m S 0 3.4 8:02.26 thunderbird-bin 20011 root 5 -10 591m 52m 50m S 3 2.6 22:47.90 vmware-vmx 4607 jjaimon 15 0 330m 42m 7584 S 2 2.1 19:34.48 firefox-bin 3967 jjaimon 15 0 114m 18m 2632 S 3 0.9 23:13.73 main-menu Load average is shown high. But, all that I have is 3-4 regular applications (firefox, gnome-terminal and thunderbird) and one VMWare instance. I also noticed that, my system returns to normal state if I restart X. I read through the pm_utils suggestions given at http://en.opensuse.org/Pm-utils but couldn't notice any difference. Here is the log from pm-utils.
