Hello,
I'm using an InfiniHost III Ex / MT25208 on Debian/Jessie and after running 'pm-suspend' and then resuming, my network stops responding. If I try to use ibstat or ibstatus then I will experience hangs and then finally an error message appears related to ib_mthca:
ib_mthca 0000:02:00.0: HW2SW_MPT failed (-16)
Here is a list of modules loaded on startup:
mlx4_ib
ib_umad
ib_ipoib
I've also tried unloading the modules before suspending like this:
/etc/init.d/opensm stop
modprobe -r ib_ipoib
modprobe -r ib_umad
modprobe -r mlx4_ib
modprobe -r ib_mthca
But when I reload the modules my ib1 interface does not appear. This happens even if I don't suspend.
Btw, I've attempted to update the firmware but I can't get anything to work. Examples:
lspci -d 15:b3 = nothing
ibv_devinfo | grep hca_id = Failed to get IB devices list: Function not implemented.
mstflint -d 02:00.0 q = -E- Cannot open Device: 02:00.0. File exists MFE_OLD_DEVICE_TYPE
plain lspci =
02:00.0 InfiniBand: Mellanox Technologies MT25208 [InfiniHost III Ex] (rev a0)
