Kernel 5.2.1-191-default on seattle:

[   30.672910] arm-smmu e0600000.smmu: Unexpected global fault, this could be serious
[   30.680475] arm-smmu e0600000.smmu:  GFSR 0x80000001, GFSYNR0 0x00000000, GFSYNR1 0x00000001, GFSYNR2 0x00000000

This gets repeated over and over, and network never comes up, which looks related.

Comment 2 Takashi Iwai 2019-08-08 13:05:29 UTC
Just a note: the thread suggested arm-smmu.disable_bypass=0 boot option as an immediate workaround.
Comment 3 Jiri Slaby 2019-11-04 12:27:48 UTC
Has this been fixed yet?
Comment 4 Andreas Schwab 2019-11-11 13:48:31 UTC
CONFIG_ARM_SMMU_DISABLE_BYPASS_BY_DEFAULT has been disabled.
