It may be\nsufficient just to do \"ls /afs\" and the oops looks something like:\n\n        BUG: kernel NULL pointer dereference, address: 0000000000000020\n        ...\n        RIP: 0010:afs_getattr+0x8b/0x14b\n        ...\n        Call Trace:\n         <TASK>\n         vfs_statx+0x79/0xf5\n         vfs_fstatat+0x49/0x62",
