The crash is triggered when the Oracle ASM disks are accessed.

Resolution

Update oracleasm to to patch 1994 (version 2.0.8_k4.4.92_6.18-3.6.1) released on 2017-12-01

Cause

Upstream kernel development has introduced commit f9cc4472c963e64493261d834155974c48c0ff88 ("block: unexport various bio mapping helpers").

As a consequence of this, Oracle ASM must now use the function 'blk_rq_unmap_user(r->r_bio)' instead of 'bio_unmap_user(r->r_bio)'.

Additional Information

A support agreement is needed in order to obtain the patch mentioned in this document.
