https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209571 Peter Eriksson <peter.x.eriksson@liu.se> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |peter.x.eriksson@liu.se --- Comment #12 from Peter Eriksson <peter.x.eriksson@liu.se> --- Just another data point:=20 We are seeing strange behaviour with some PCIe SSDs - Intel DC P3520 which randomly/after a while seems to hang (go dead) - so dead that they disappear from the PCI bus and requires a power off / wait until caps have drained / power on to revive... But this happens on 11.2 - and some other folks here = have seen similar problems on Linux. So I suspect this is not really OS-related. We've also had problems with the SATA version (Intel S3520) where they occasionally freeze up on us (and go "silent" on the SATA/SAS port). Often = if we wait long enough (days/a week or so) they will revive themselfs and start working again... --=20 You are receiving this mail because: You are the assignee for the bug.=
