It is\ndisallowed to do that in IRQ context or with BH disabled. Otherwise, we\nhit this line in vunmap, causing the crash:\n  BUG_ON(in_interrupt());\n\nThis patch reenables BH to release the buffer.\n\nLog messages when the bug is hit:\n kernel BUG at mm/vmalloc.c:2727!\n invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\n CPU: 6 PID: 1462 Comm: NetworkManager Kdump: loaded Tainted: G          I      --------- ---  5.14.0-119.el9.x86_64 #1\n Hardware name: Dell Inc.
