If you can load acpi-cpufreq, you probably don't use the latest jaunty kernel.

[Bug 365798] Re: cpu frequency scaling not supported after upgrading to 9.04
Mats, the bug you describe is a different one. This one is about frequency scaling being not supported, while your output states 5 supported frequency steps. I've solved the problem on my Asus P5B-E motherboard but upgrading to the latest BIOS. It still persists with the Quadcore and Atom machines that I've tested. Since quite a few people seem to be able to solve this via BIOS up- or downgrades, it seems Linux / Ubuntu is not the one to blame. -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1922466] [NEW] Writeback not flushing to disk in 4.15.0-137-generic and above
Public bug reported: Hi! We've come across some interesting behaviour in kernel 4.15.0-137.141~16.04.1 and above. After booting a fresh Ubuntu 16.04 instance on AWS, we replace the AWS kernel with "linux-image-4.15.0-140-generic" (4.15.0-140.144~16.04.1) and reboot. Then we generate some I/O by running fio for a while: fio --name=random-write --ioengine=posixaio --rw=randwrite --bs=64k --size=256m --numjobs=16 --iodepth=16 --runtime=3600 --time_based --end_fsync=1 It does't matter whether fio is run against the boot disk or an attached secondary disk. After stopping fio we notice that some pages are stuck in "writeback" and are apparently not flushing to disk: # lsb_release -rd Description:Ubuntu 16.04.7 LTS Release:16.04 # cat /proc/vmstat | grep "nr_writeback " nr_writeback 80 # cat /proc/meminfo | grep Writeback: Writeback: 320 kB This doesn't clear, not even days later. Running more fio only increases the amount of writeback pages. Downgrading the kernel to 4.15.0-136.140~16.04.1 resolves the issue, no writeback pages getting stuck. Going over the kernel changelog, I can see that between -136 and -137 the following patchset was applied, but I'm not sure whether it is related to the issue: https://www.spinics.net/lists/stable/msg435893.html Kernels 4.15.0-137-generic and above took down our Ceph cluster, because it seems that when the amount of "writeback" reaches the buffer ceiling of "dirty_bytes", all subsequent writes to the disk are incredibly slow. This is from an idle production system (not on AWS) running 16.04 with kernel 4.15.0-139-generic: # lsb_release -rd Description:Ubuntu 16.04.4 LTS Release:16.04 # cat /proc/sys/vm/dirty_bytes 629145600 # cat /proc/sys/vm/dirty_background_bytes 314572800 # cat /proc/meminfo | grep Writeback: Writeback:572108 kB # dd if=/dev/zero of=/test bs=1M count=10; rm /test 10+0 records in 10+0 records out 10485760 bytes (10 MB, 10 MiB) copied, 126.529 s, 82.9 kB/s Could there be a bug in kernel 4.15.0-137-generic and above?

[Bug 550559] Re: hdd problems, failed command: READ FPDMA QUEUED
I'm also seeing "failed command: WRITE FPDMA QUEUED" using a GA 990FXA- UD7 board with Crucial m4 SSDs connected to the Southbridge SATA controller (ATI SB950) on oneiric . Sometimes this error would crash the machine (the RAID5 module actually), sometimes it will just reset the SATA link and keep going. A workaround that solves the issue for me is to go to the BIOS and disable "SATA3.0 Mode" for the southbridge SATA. This reduces the SATA link speed to 3Gbps, although Linux still reports 6Gpbs in the kernel log. I'm using a SATA drive bay from Thermaltake. Maybe the additional connectors in there degrade the SATA link in a way that makes SATA3 unreliable. This is just speculation, I didn't test it when the drives are directly connected to the mainboard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/550559 Title: hdd problems, failed command: READ FPDMA QUEUED To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
