As reported on dev ML, I am experiencing file "strange" filesystem errors since kernel 5.1.6. For now, I am not 100% sure this is not an hardware problem as it only happens in one system. It is a 2009 Asus EeePC with 2 SSD disks. This report is here for further investigation.
Created attachment 11062 [details] dmesg showing a kernel bug It also shows an error in one /dev/sdb sector, while a full read of the SSD disks shows no problem...
The important lines from that attachment appear to be ... [ 636.459610] sd 1:0:1:0: [sdb] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT [ 636.459626] sd 1:0:1:0: [sdb] tag#0 CDB: Test Unit Ready [ 636.459633] print_req_error: I/O error, dev sdb, sector 10460616 flags 80700 It could be a faulty drive, cable (dirty or loose connections, broken wire that sometimes connects), or a fault in the drive controller. Whichever one it is, it looks like a hardware failure, not a software problem.

I should have added, that it can appear to only affect the one kernel, as that kernel is using files written into a bad block within the ssd drive.
Closing as it did not happen again...
