Pm80xx driver is connected with OS upper layer scsi_transport_sas / libsas / ses drivers. > > We’ve added the support for SLES 12 SP2 - 4.4.21-default OS. Pm80xx driver works fine with cascaded second expander. > > We were facing kernel crash issue with SLES 12 SP3 kernel - 4.4.70-default when we had connected cascaded second expander. > > To explain the scenario where we face this issue. > We have HBA card and two expanders connected in cascade with another. > With cascaded second expander(remote PHY ) if we connect drives and switch off the expander OS crashes with libsas. > > Please find below crash dump > Hi Raj, Seems upstream has similar bug: Dan and guys from Huawei were working on that, the patchset improved the situation but but is not fully fixed. Maybe you can pick up wangyijing's latest work, and fix the bug for all. https://lkml.org/lkml/2017/7/12/683 KR, Jack > > > [ 1194.413817] > [ 1194.413818] Leftover inexact backtrace: > > [
