Subject: There are not enough CPU0 APIC IRQs while doing IRQ migration during S3
HI all,
I encountered an issue while doing S3, it shows below message and then
failed to enter S3
[ 106.731140] CPU 31 has 116 vectors, 85 available. Cannot disable CPU
[ 106.731551] ACPI: \_PR_.C01F: Found 2 idle states
[ 106.732610] Error taking CPU31 down: -28
[ 106.732612] Non-boot CPUs are not disabled
CPU: AMD Ryzen Threadripper PRO 3955WX 16-Cores
Kernel: v5.19-rc7
There are 5 PCI to 4 type-c ports USB cards on the machine, and It
wouldn't lead to the issue if only 4 cards are plugged. So, it looks
like it can't handle 5 cards, and failed on the IRQ migration.
The workaround provided by kaiheng is to release the irq while
suspending and request irq while resuming.
I'm wondering do we have a better solution for this kind of issue?
Thanks.
