Bug ID: 297549
Summary: panic: zfs zfs_btree_remove_idx / bt_shift_leaf
Product: Base System
Version: 15.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Under load (chromium poudriere build) my system panics in zfs. I recently
upgraded from 15.0 to 15.1 and am currently running 15.1-RELEASE-p2. The
machine in question would have no issues with heavy builds in the past.
