Description of problem: optical mouse does not function after the kernel begins to boot. also, booting fedora 12 beta live media from a usb stick does not work. i found this https://lists.linux-foundation.org/pipermail/bugme-new/2006-May/014325.html and tried adding mem=2g to my boot options and now the mouse works. i have attached a portion of dmesg that looks suspect but can provide you with any more logs or output that you require. dmesg: usb 5-1: new low speed USB device using uhci_hcd and address 3 nommu_map_single: overflow 137c1b0d0+8 of device mask ffffffff nommu_map_single: overflow 136c047c0+64 of device mask ffffffff nommu_map_single: overflow 135cb8648+8 of device mask ffffffff nommu_map_single: overflow 136c047c0+64 of device mask ffffffff nommu_map_single: overflow 135cb8648+8 of device mask ffffffff nommu_map_single: overflow 136c047c0+64 of device mask ffffffff usb 5-1: device descriptor read/64, error -32 nommu_map_single: overflow 135cb8648+8 of device mask ffffffff nommu_map_single: overflow 1355dff00+64 of device mask ffffffff nommu_map_single: overflow 135cb8648+8 of device mask ffffffff nommu_map_single: overflow 1355dff00+64 of device mask ffffffff nommu_map_single: overflow 137c1b0d8+8 of device mask ffffffff nommu_map_single: overflow 1355dff00+64 of device mask ffffffff usb 5-1: device descriptor read/64, error -32 usb 5-1: new low speed USB device using uhci_hcd and address 4 nommu_map_single: overflow 137c1b0d8+8 of device mask ffffffff nommu_map_single: overflow 137c38f80+64 of device mask ffffffff nommu_map_single: overflow 135cb85c8+8 of device mask ffffffff nommu_map_single: overflow 137c38f80+64 of device mask ffffffff nommu_map_single: overflow 135cb85c8+8 of device mask ffffffff nommu_map_single: overflow 137c38f80+64 of device mask ffffffff usb 5-1: device descriptor read/64, error -32 nommu_map_single: overflow 135cb85c8+8 of device mask ffffffff nommu_map_single: overflow 137d0e980+64 of device mask ffffffff nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff nommu_map_single: overflow 137d0e980+64 of device mask ffffffff nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff nommu_map_single: overflow 137d0e980+64 of device mask ffffffff usb 5-1: device descriptor read/64, error -32 usb 5-1: new low speed USB device using uhci_hcd and address 5 nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff usb 5-1: device not accepting address 5, error -32 udev: starting version 145 usb 5-1: new low speed USB device using uhci_hcd and address 6 nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff nommu_map_single: overflow 137c1b0e0+8 of device mask ffffffff Version-Release number of selected component (if applicable):kernel 2.6.31.5-96.fc12.x86_64 How reproducible: always Steps to Reproduce: 1.boot machine using more than 2gigs of ram 2. 3. Actual results:usb mouse and memory stick do not work Expected results: Additional info:
Please post the entire dmesg. And try adding "intel_iommu=off" to the boot options next time, instead of "mem=2g".
Also try "iommu=soft"
I have this problem too, adding intel_iommu=off fix this for me. This bug is related (identical) with this bugs: Bug 522668 - No USB mouse function Bug 530455 - Intel 82801I (ICH9 Family) USB and USB2 controller does not function thanks for this advice :D Is possible to fix this in kernel? Should I use iommu=soft instead?
Created attachment 367844 [details] dmesg after fix kernel with intel-iommu=off dmesg after fix kernel with intel-iommu=off, whole usb stack work OK
Created attachment 367847 [details] dmeseg log with standard kernel options Whole USB stack is broken (mouse, usb disks, bluetooth) kernel 2.6.31.5-117.fc12.x86_64
iommu=soft also fix this problem, which one is better? This bug apply also to kernel 2.6.31.5-122.fc12.x86_64
Created attachment 367855 [details] dmesg with iommu=soft
