So a little nut to crack for my #linux bubble: I am running #mintlinux on my external Thunderbolt SSD on the 2013 iMac. Problem is: When I suspend and then resume, the TB SSD does NOT wake up. System hangs -- because there is no root FS anymore!
I already tried iummu=soft and pcie_aspm=off in the grub defaults:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft pcie_aspm=off"
But that does nothing to help. Any other ideas how to wake the sleeping princcess?
