Bug ID: 200740
Summary: KASSERT panic due to race between GEOM tasting and
withering
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern

wither-taste.diff
disk_gone() can happen at any time due to hardware failures, and start
withering GEOM devices. If something closes a device at about the same time,
g_access() can queue an event that will call g_new_provider_event(), and the
provider may have G_PF_WITHER set by the time g_new_provider_event() gets
called, which panics a debug kernel.
The attached patch replaces the KASSERT with a check of G_PF_WITHER, and just
returns if it's set, since it doesn't make sense to taste a device that's going
away.
