[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
Hi Paulo, Thanks for all that research and feedback. Just to provide some additional information, USB_SUSPEND is enabled by default in the Ubuntu Hardy Kernel: [EMAIL PROTECTED]:~/ubuntu-hardy/debian/config$ grep -rn USB_SUSPEND * amd64/config:2875:CONFIG_USB_SUSPEND=y i386/config.386:1995:CONFIG_USB_SUSPEND=y i386/config.server:1997:CONFIG_USB_SUSPEND=y i386/config.virtual:490:# CONFIG_USB_SUSPEND is not set i386/config.generic:1991:CONFIG_USB_SUSPEND=y ia64/config:2349:CONFIG_USB_SUSPEND=y lpia/config:2657:CONFIG_USB_SUSPEND=y powerpc/config:2521:CONFIG_USB_SUSPEND=y I'll also provide a link to the document you reference in case others don't know where to find it: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/usb /power-management.txt;h=b2fc4d4a99177be7bd48dce560d1f28417c60aa9;hb=HEAD The solution you've found appears to have resolved the issue. From what was mentioned in the kernel doc, it's unlikely that the power/level attribute will be set to default to auto because of the issues it raises so I'll be closing this report.

[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
I have been analyzing the problem using a 2.6.24 kernel and I found where the problem is. As I thought, devices-USB support-USB selective suspend/resume and wakeup (USB_SUSPEND) is needed. Besides, for later kernels, /sys/bus/usb/devices/n-n/power/level is initialized with on instead of auto. Doing 'echo auto /sys/bus/usb/devices/n-n/power/level' fixes the problem. I don't know the reason for this to have changed however. May be upstream has something to say about this. ** Changed in: linux (Ubuntu) Status: Incomplete = In Progress -- bug or feature request - kernel: Removing modules do not turn off devices https://bugs.launchpad.net/bugs/150783 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
Well ... I had a few problems in order to boot. The current release failled to recognize my graphic card and did not install radeon module. Perhaps because of this it also generated a wrong xorg.conf. So loading radeon manually did not work. After loading gdm my system displayed a black screen with some garbage on top and the keyboard was completely frozen except for kernel magic keys (ctrl+alt+prt sc+...). Anyway I could boot without splash and typing several ctrl-c/alt-f1 when the gdm began to startup I could get a console (BTW, any other way to boot without X?). I removed all rt2* modules but the wifi USB card still kept its led on. So, the bug still exists.

[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
Hi All, Sorry for the extremely delayed response. The Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Also note that we will keep this report open against the actively developed kernel. However against linux-source-2.6.22 this report will be close as it does not qualify for an SRU candidate. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .

[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
I could see that the latest K sources already have USB_SUSPEND. Unfortunately they do not work however (!). Removing the wireless module does not turn off the led from my USB wireless card. I have been playing with the kernel options trying to find any other reason/configuration without any success so far! I am sure that USB_SUSPEND is needed although it seems to be not enough. Does anybody have any suggestion I could check? -- bug or feature request - kernel: Removing modules do not turn off devices https://bugs.launchpad.net/bugs/150783 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

i've had this issue sort of myself an example is that i blacklisted midi and supertux still plays midis which is odd because there is no midi modules to be found in lsmod. So i'm guessing this is similiar and if so then it's a confirm from me also. -- bug or feature request - kernel: Removing modules do not turn off devices https://bugs.launchpad.net/bugs/150783 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

What version of kernel version are you using? Also, can somebody find the package that this affects... I thought it would be linux-image or kernel something, but I couldn't find it in the choose package interface -- bug or feature request - kernel: Removing modules do not turn off devices https://bugs.launchpad.net/bugs/150783 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 150783] Re: bug or feature request - kernel: Removing modules do not turn off devices
kernel 2.6.22-13. I think any recent kernels have that option. The modules involved are those related with rt2570 legacy usb wireless drivers or ndiswrapper+rt2500usb, at least. BTW, my ASUS wl-167g USB does not work with rt2x00usb drivers. It works with rt2570 legacy (cvs) and with ndiswrapper. I'll wait for newer rt2x00 versions before filing a new bug. -- bug or feature request - kernel: Removing modules do not turn off devices https://bugs.launchpad.net/bugs/150783 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
