Hi, I went ahead and applied your kernel changes to my primary lucid installation which uses the Intel G41M4-F motherboard that I originally had the problem on. This is the same hardware I first tested your changes on except that this time I updated the lucid OS release installed on the internal SATA harddrive rather than the test instance of Lucid that I installed on the USB drive to pre-test your changes. I didn't see the memory leaks I saw earlier duing the test installation. However, I did see some fail messages that I didn't see earlier. Are those normal? Please see attached.
However, on a better note, just as before with the test instance, I now see better USB read speeds on my primary Lucid Installation, where I originally noticed the slow read speeds. owner@Pluto:~$ sudo hdparm -tT /dev/sdb [sudo] password for owner: /dev/sdb: Timing cached reads: 2920 MB in 2.00 seconds = 1460.61 MB/sec Timing buffered disk reads: 106 MB in 3.02 seconds = 35.08 MB/sec owner@Pluto:~$ I also copied a 4 GB file to and from the external USB hard drive to confirm that Nautilus reported read and write speeds of approx 30 MB/s. The problem appears to be fixed. Thanks for following up on this problem. ** Attachment added: "More Messges From Lucid Kernel Installation Fix" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/624510/+attachment/2884658/+files/moreMessagesFromKernelInstallation.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/624510 Title: Copying To USB Is Very Slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/624510/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
