So we had today our weekly Debian kernel team meeting. One observation now is that this actually might indicate there are two distinct bugs. One affecting Kingston SSD on 6.1, and one affecting Lexar SSD on 6.5 and later. Now we do not patch NVMe in Debian so this can be indication enough that it is already an upstream issue, but to be sure, can you re-test this with upstream versions, 6.1.115 and ideally something around 6.11.5 upstream (+ mainline if possible). If you can then still reproduce the issue, our suggestion is to now report the issues upstream. For a start including the NVMe maintainers, so from MAINTAINERS file: NVM EXPRESS DRIVER M: Keith Busch <kbu...@kernel.org> M: Jens Axboe <ax...@fb.com> M: Christoph Hellwig <h...@lst.de> M: Sagi Grimberg <s...@grimberg.me> L: linux-n...@lists.infradead.org S: Supported W: http://git.infradead.org/nvme.git T: git git://git.infradead.org/nvme.git F: Documentation/nvme/ F: drivers/nvme/common/ F: drivers/nvme/host/ F: include/linux/nvme-*.h F: include/linux/nvme.h F: include/uapi/linux/nvme_ioctl.h Can you keep us in the loop?
