I installed a fresh copy of Kubuntu 22.04 on a brand new 500Gb PNY CS900 SSD. I've been noticing a bunch of the following errors on system shutdown, and they're a bit worrying:
...Apr 22 15:34:07 sluggo kernel: blk_update_request: I/O error, dev sdb, sector 110924048 op 0x0:(READ) flags 0x80700 phys_seg 17 prio class 0...
According to smartctl, there's nothing wrong with this
drive.
