Public bug reported: [Impact] When creating 8 accelerated network interfaces on Azure and attaching them to a VM from kernel message, it fails to handle IRQ data in hv_pci as below: [ 15.533530] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.539856] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.546261] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.552781] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.560177] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.566631] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005
And 2 VFs are consistently missing, only 6 seem to be working [Fix] The fix was merged to upstream hyperv tree: https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/commit/?h=hyperv-fixes&id=f134588e4cebaecdeafbbb19317517ea9b729aa9 [Test Plan] 1. Create 8 NICs in azure with accelerated networking enabled 2. Launch a VM with all 8 attached 3. Check the output from VM [Where problems could occur] The patch is to use the correct type for the variables and reviewed by upstream There shouldn't be any problem ** Affects: linux (Ubuntu) Importance: High Assignee: gerald.yang (gerald-yang-tw) Status: In Progress ** Affects: linux (Ubuntu Focal) Importance: Undecided Assignee: gerald.yang (gerald-yang-tw) Status: In Progress ** Affects: linux (Ubuntu Jammy) Importance: Undecided Assignee: gerald.yang (gerald-yang-tw) Status: In Progress ** Affects: linux (Ubuntu Kinetic) Importance: Undecided Assignee: gerald.yang (gerald-yang-tw) Status: In Progress ** Changed in: linux (Ubuntu) Assignee: (unassigned) => gerald.yang (gerald-yang-tw) ** Changed in: linux (Ubuntu) Status: New => In Progress ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Also affects: linux (Ubuntu Kinetic) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Focal) Assignee: (unassigned) => gerald.yang (gerald-yang-tw) ** Changed in: linux (Ubuntu Jammy) Assignee: (unassigned) => gerald.yang (gerald-yang-tw) ** Changed in: linux (Ubuntu Kinetic) Assignee: (unassigned) => gerald.yang (gerald-yang-tw) ** Changed in: linux (Ubuntu Focal) Status: New => In Progress ** Changed in: linux (Ubuntu Jammy) Status: New => In Progress ** Changed in: linux (Ubuntu Kinetic) Status: New => In Progress -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1995684 Title: Fail to handle IRQ data in hv_pci and lead to attach 8 VF to VM fail Status in linux package in Ubuntu: In Progress Status in linux source package in Focal: In Progress Status in linux source package in Jammy: In Progress Status in linux source package in Kinetic: In Progress Bug description: [Impact] When creating 8 accelerated network interfaces on Azure and attaching them to a VM from kernel message, it fails to handle IRQ data in hv_pci as below: [ 15.533530] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.539856] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.546261] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.552781] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.560177] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 [ 15.566631] hv_pci 1f4aa2a4-aff1-40af-8547-12f13bf19608: Request for interrupt failed: 0xc0350005 And 2 VFs are consistently missing, only 6 seem to be working [Fix] The fix was merged to upstream hyperv tree: https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/commit/?h=hyperv-fixes&id=f134588e4cebaecdeafbbb19317517ea9b729aa9 [Test Plan] 1.
