- Subject changed from Suspend to RAM fails to recursive mutex enter in ahci
Updated by Hans Rosenfeld over 4 years ago
Both ahci_em_quiesce() and ahci_em_suspend() try to grab ahcictl_mutex. The code in ahci_detach() already holds it when it calls ahci_em_suspend().

Thanks for the patch, Hans.
With the patch from #3 I got a bit further (to some other problem):
System is being suspended WARNING: Unable to suspend device pci17aa,21fa@14. WARNING: Device is busy or does not support suspend/resume. WARNING: xhci0: abort command timed out: resetting device ^Mpanic[cpu2]/thread=ffffff001e695c40: XHCI runtime reset required ffffff001e695b60 xhci:xhci_soft_state+37d7a47a () ffffff001e695c20 genunix:taskq_thread+2d0 () ffffff001e695c30 unix:thread_start+8 ()
Rest of the info attached.
