Hi, I ran into a bug with a very similar call trace, also when copying files with rsync from a filesystem mounted using ntfs3. I was able to reproduce it on both the default Arch Linux kernel (5.15.11-arch2-1) and on mainline 5.16-rc7. > This is where the real bug happened. It would be helpful if you > could run > ./scripts/faddr2line /path/to/vmlinux page_cache_ra_unbounded+0x1c5/0x250 > > It'll spit out something like: > page_cache_ra_unbounded at mm/readahead.c:241 > > but probably a different line number from that. I had to rebuild the vmlinux of my kernels in order for this to work but the output for the page_cache_ra_unbounded line is below the dmesg outputs. 5.15.11-arch2-1 dmesg: [ 486.360050] BUG: unable to handle page fault for address: ffffff8306d925ff [ 486.360083] #PF: supervisor instruction fetch in kernel mode [ 486.360113] #PF: error_code(0x0010) - not-present page [ 486.360142] PGD 171815067 P4D 171815067 PUD 0 [ 486.360160] Oops: 0010 [#1] PREEMPT SMP PTI [ 486.360177] CPU: 2 PID: 1129 Comm: rsync Tainted: G OE 5.15.11-arch2-1 #1 03010ffba27108079ccfa4d61c5b01422e5fb7c7 [ 486.360216] Hardware name: ASUSTeK COMPUTER INC.
