https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263704 Bug ID: 263704 Summary: Panic because device went away with XPT_ATA_IO pending Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: imp@FreeBSD.org we can drop all references to the device (causing us to go through camperiphfree and destroy the path) while we have an I/O pending in the ata= _da state machine (usually in state ADA_STATE_RAHEAD with ATA_SETFEATURES ATA_SF_ENAB_RCACHE command). It's not clear why the reference that we take = out to do the reprobe isn't effective at blocking this. By retrying this condit= ion, though we avoid this bug (at least more often, I don't have a good reproduc= tion test case, I just see this panic a few times a month at work on systems that have transient disk errors on ahci connected SATA SSDs). --=20 You are receiving this mail because: You are the assignee for the bug.=
