BTW, looks it isn't related with specific filesystem, and from the recent triger, it happened when walking path inside proc filesystem:

So it might be one arm64 dependent issue. -- 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/1440536 Title: Oops __d_lookup+0x88/0x194 Status in The Linux Kernel: Unknown Status in linux package in Ubuntu: Triaged Status in linux source package in Vivid: Triaged Bug description: This started happening on a Mustang board after upgrading to 3.19.0-9.9 and persists in 3.19.0-11.
