My Raid Array don't like new kernels

  • Hello,


    My NAS turn on OMV 4.1.17-1 Arrakis.


    I have a little (or not) problem with my Raid 6.
    The array is composed of 11 HDD, some are wired on the motherboard and the other on a SataCard (Kalea-Informatique PCIe 10xSATA 3.0 found on Amazon)


    If I keep my kernel at 4.14.0-0.bpo.3-amd64, I have no pb: Array is displayed as clean in OMV Gui; CIFS, FTP or other services works like a charm.
    If I upgrade my kernel to 4.18.0-0.bpo.1-amd64, 4.18.0-0.bpo.3-amd64 or 4.19.0-0.bpo.1-amd64, the Array is diplayed as Active in the Gui. Also if I try CIFS or FTP folder display, it stucked for long long time.


    This is then displayed in my syslog:


    Code
