[Bug 1497383] Re: While copying from hdd to hdd or hdd to usb ubuntu freezes


Abdul Rehman, at your earliest convenience, could you please test the
latest upstream kernel available from the very top line at the top of
the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
(the release names are irrelevant for testing, and please do not test
the daily folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

  While copying from hdd to hdd or hdd to usb ubuntu freezes

Status in linux package in Ubuntu:

Bug description:
  WDC WD7500BPVT 750GB Advanced format HDD
  deadline scheduler is selected
  parted informs that partitions are aligned
  logical sectors are 512B while physical sectors are 4096 bytes
  hdparm informs speed 96MB/s
  Programs startup is slow.
  S.M.A.R.T assessment is OK.
  HDD operations make system unusable.

  WORKAROUND: Change default dirty_ratio = 60 to 5, and
  dirty_background_ratio = 40 to 10. However, this slows down HDD R/W
