https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265222 Bug ID: 265222 Summary: T480 zfs checksum mismatch error Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: mail@malisek.org I encounter severe i/o related issues on my thinkpad T480=20 Those seem to be similar to #239801 #241476 & #262421 although I'm not using any special/obscure drivers on this thinkpad. After clean install and configuration of FreeBSD 13.1-release following err= ors appear after I extract big archive or decide to reinstall big package. zpool status -v pool: zroot state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A scan: scrub repaired 0B in 00:00:38 with 3 errors on Thu Jul 14 22:13:49 = 2022 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 ada0p4.eli ONLINE 0 0 12 errors: Permanent errors have been detected in the following files: When i scrub the drive following errors appear in log: Jul 14 22:13:33 ltop ZFS[59816]: pool I/O failure, zpool=3Dzroot error=3D97 Jul 14 22:13:33 ltop ZFS[60942]: checksum mismatch, zpool=3Dzroot path=3D/dev/ada0p4.eli offset=3D77657673728 size=3D131072 Jul 14 22:13:49 ltop ZFS[99701]: pool I/O failure, zpool=3Dzroot error=3D97 Jul 14 22:13:49 ltop ZFS[621]: checksum mismatch, zpool=3Dzroot path=3D/dev/ada0p4.eli offset=3D193825124352 size=3D131072 Jul 14 22:13:49 ltop ZFS[2696]: pool I/O failure, zpool=3Dzroot error=3D97 Jul 14 22:13:49 ltop ZFS[4749]: checksum mismatch, zpool=3Dzroot path=3D/dev/ada0p4.eli offset=3D197592481792 size=3D131072 I decided to try few different things to verify whether it's hw related iss= ue or not: 1. I tried using spare motherboard (and cpu), spare sata ssd (new) and spare cable for ssd that I managed to borrow. Errors on FreeBSD still persists. neither memtest86+ or thinkpad bios diagnosis tools reported any issues with the hardware. both ssds tried are new and no error was reported by smartctl 2. I tried downloading several big distro iso files on windows 10 and do checksuming there manually. None of those checksums failed on windows so it seems to be freebsd issue. 3. I did not try running and testing linux with openzfs yet. Worth note: 1. pkg also reports randomly checksum mismatch too (especially for big packages) which causes install to fail 2. This seems to happen only when X11 is running. No such error occurred wh= en my post install script installs packages when X is not even present. 3. System even crashed randomly several times on previous install due to partial corruption of drm-kmod. sysctl.conf https://file.malisek.org/1zcmumjm.conf loader.conf https://file.malisek.org/wybkf9dx.conf rc.conf https://file.malisek.org/1ew82d2t.conf --=20 You are receiving this mail because: You are the assignee for the bug.=
