This bug is awaiting verification that the linux- hwe-6.2/6.2.0-23.23~22.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

No vmd probe error should be found in dmesg. [Where problems could occur] This is the way it should have been done. [Other Info] This is not reproducible with v6.0 or older kernels, so only Lunar and oem-6.1 are nominated for fix. OEM-6.0 patch goes to Gerrit instead. ========== original bug report ========== vmd may fail to create sysfs entry while `pci_rescan_bus()` called in some other drivers like wwan. This happens after bug 2002089 re-added pci rescan feature back to wwan t7xx driver to support firmware updates via devlink. t7xx may call `pci_rescan_bus()` with proper locks, but vmd doesn't. sysfs: cannot create duplicate filename '/devices/.../resource0' Call Trace: <TASK> sysfs_warn_dup.cold+0x17/0x34 sysfs_add_bin_file_mode_ns+0xc0/0xf0 sysfs_create_bin_file+0x6d/0xb0 pci_create_attr+0x117/0x260 pci_create_resource_files+0x6b/0x150 pci_create_sysfs_dev_files+0x18/0x30 pci_bus_add_device+0x30/0x80 pci_bus_add_devices+0x31/0x80 pci_bus_add_devices+0x5b/0x80 vmd_enable_domain.constprop.0+0x6b7/0x880 [vmd] vmd_probe+0x16d/0x193 [vmd] To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2011389/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
