[Bug 119730] Re: Slow SATA performance
Hi all, I was moving disks around on my motherboard because the SATA cables blocked a video card. Two disks were placed on a secondary SATA controller on the motherboard which I hadn't used before. This has caused the slowness to resurface, with the mainline kernel. Previously, all the disks were on an "82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA AHCI Controller", using driver "ahci", capabilities "storage msi pm bus_master cap_list emulated", configuration "driver=ahci latency=0 module=ahci". According to lshw. In the rearrangement, two disks were placed on a "JMicron 20360/20363 AHCI Controller", also using driver "ahci", capabilities "storage pm pciexpress bus_master cap_list emulated", configuration "driver=ahci latency=0 module=ahci". Before installing mainline, there was both IO and overall system lag with the Intel controller. With mainline, the Intel behaves fine, but the JMicron turns out to be slow. (To the point where I personally consider it broken.)

Hi, Bump. I've now installed the mainline kernel on at least four machines: One Core 2 Duo, one Core 2 Quad and an i7 machine. 64-bit Ubuntu versions 8.10 and 9.04. In all cases, the broken I/O has been fixed by the mainline kernel install. -- Slow SATA performance https://bugs.launchpad.net/bugs/119730 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

@ngsupb, We used the vanilla versions corresponding to whatever was the stable Ubuntu kernel at the time, for that release. (We didn't go to 2.6.30.)

[Bug 119730] Re: Slow SATA performance
Hi, I had terribly fluctuating speeds on the SATA drives in my machine, and it sometimes the entire OS would stall and sometimes not. I'm not 100% sure this Ubuntu bug report applies to my situation. I'd just like to state, however, that I just updated my BIOS to the latest version, which the manufacturer claims has 'updated super i/o code'. Now all SATA disks perform as expected. I've got a Gigabyte P35-DS4R, and I installed BIOS version F14C. -- Slow SATA performance https://bugs.launchpad.net/bugs/119730 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 251830] [NEW] Mouseemu installed, not wanted
Public bug reported: Hi, I have an Intel Mac Mini, a Core Duo 1.66 GHz. I'm running Ubuntu 8.04.1 on it. Hardware info: http://www.everymac.com/systems/apple/mac_mini/stats/mac_mini_cd_1.66.html Mouseemu was installed by the Ubuntu installer, and was running on the machine. As a Mini is not a laptop, mouseemu caused the mouse to stop / lag when I typed stuff on the keyboard. It was kind of hard to discover what was going on. There's some small fix somewhere in the hardware detection routines I guess - the Mac Mini seems to be reported as a laptop, though it doesn't have a trackpad. ** Affects: ubuntu Importance: Undecided Status: New -- Mouseemu installed, not wanted https://bugs.launchpad.net/bugs/251830 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 236343] Re: Firefox 3 Segmentation fault: npviewer.bin: assertion `style-> attach_count > 0' failed
I think the bug has more to do with the gail message than the assertion itself. I don't really know what gail is, but http://directory.fsf.org/project/GAIL/ says "'GAIL' is a GTK+ module that provides accessibility support for GTK+ and libgnomecanvas". A few programs started crashing for me yesterday - today I remembered that I had enabled Assistive Technologies.

[Bug 32906] Re: sudo shouldn’t ABSOLUTELY NEED to look up the host it’s running on
The sudo+hostname bug/inconvenience happened to me. I hosed my hosts file when upgrading from 7.04 to 8.04. Sudo didn't want to do anything, but gksudo worked fine. The network-dependent sudo failed, but the X11-dependent gksudo was OK.
