https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224841 --- Comment #21 from Gustavo Romero <gromero@br.ibm.com> --- (In reply to Wojciech Macek from comment #20) Hi, Using the current HEAD: commit 46822a0e45dc8e37132231ed6a4f95fe6fdf6d68 (HEAD -> master, origin/mas= ter, origin/HEAD) Author: wma <wma@FreeBSD.org> Date: Tue Jan 23 08:07:00 2018 +0000 PowerNV: send MSI_EOI always after MSI unmask MSI/MSI-x interrupts are edge-triggered. If an interrupt arrives when IRQ line is masked, it will be lost and will never recover. Perform MSI_EOI always after unmask to give a chance for PHB/XICS to send an interrupt again if MSI/MSI-x pending bit is set in MSI/MSI-x BAR space.
