[Kernel-packages] [Bug 2039755] Re: lernel crashes in CIFS code
This has started happening for me since upgrading linux-image-generic- hwe-22.04 from 6.2.0.31.31~22.04.8 to 6.2.0.32.32~22.04.9. It is still happening currently with 6.2.0.36.37~22.04.14. I get this issue typically when (auto-) mounting or unmounting a CIFS share that has VFS, resulting in a NULL pointer dereference in the kernel and a soft lockup in the CPU.
