Bug ID: 266054
Summary: panic: page fault in
sys/ofed/drivers/infiniband/core/ib_cma.c:1060
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
I'm on CURRENT on 27c6009e7237597a502521e0255a74164ff6bea7 with our internal
irdma driver (newer than in vanilla FreeBSD, but with no other modifications).
I do (yes, wrong IP in rping):
ifconfig ice0 100.0.0.117/24
rping -svda 100.0.0.116
Instead of the usual error, there is an instant panic after:
created cm_id 0x128dd9c99000
The panic is:
