Hello,

kernel test robot noticed "kvm-unit-tests.vmx_apic_passthrough_tpr_threshold_test.fail" on:

commit: 4cad9f87876a943d018ad73ec3919215fb756d2d ("KVM: x86: Wake vCPU for PIC interrupt injection iff a valid IRQ was found")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

in testcase: kvm-unit-tests
version: kvm-unit-tests-x86_64-f77fb696-1_20250207

config: x86_64-rhel-9.4-func
compiler: gcc-12
test machine: 4 threads 1 sockets Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz (Ivy Bridge) with 8G memory

(please refer to attached dmesg/kmsg for entire log/backtrace)



If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

Known issue, (should be) fixed by commit 982caaa11504 ("KVM: nVMX: Process events
on nested VM-Exit if injectable IRQ or NMI is pending") in Paolo's and Linus' trees.
