Hello, I understand that kmod-hfsplus is now no longer maintained, so that reporting this is unlikely to get any attention; my motivation in reporting it is to ensure that the existence of this bug is recorded somewhere in case anybody looks at this module again. Versions in use: kernel.x86_64 5.14.0-70.17.1.el9_0 (rockylinux 9.0) kmod-hfsplus.x86_64 0.4-1.el9 from elrepo hfsplus-tools.x86_64 540.1.linux3-26.el9 from elrepo How reproducible: always Steps to produce: 1. Format a partition on each of two memory sticks with hfsplus using mkfs.hfsplus; 2. Mount one of them on <mnt1> and the other on <mnt2>; 3. Populate <mnt1> with the contents of a standard rockylinux live stick's hfsplus partition (partition 3 of such a stick) (although the exact contents of the filesystem may not be important); 4. cp -a <mnt1>/* <mnt2> Result: System crashes, leaving nothing in /var/log/messages. Attached: kexec-dmesg.log and vmcore-dmesg.txt from the crash dump (vmcore is too large). Additional information: I've tried doing the same with vfat partitions and the same problem does not occur. Nor does it occur if -r is substituted for -a in the copy. Nor does it occur if copying is from ext4 on disk to stick or vice versa. I'm afraid that updating to later kernels and the like is beyond what I have time (or expertise) to contribute - apologies. Roger Sewell.
