System hangs on 3rd icon after upgrade

[Starcrasher]

The system is a nightly x64 (hrv57033) running in KVM/QEmu. It is running fine with previous state. Joined are 2 syslogs first boot and after forcing reinit.

usb error xhci -1: Host Controller halted

Will check again after today upgrade.

Appears to be a problem with MSI-X interrupts.

I received a report from X512 about a problem like this, too. I have tested in QEMU without any issues. What is your exact QEMU/KVM configuration?

If it can help this is QEMU emulator version 5.2.0 (qemu-5.2.0-4.mga8) on 'regular' Mageia x64.

After updating to hrev57038, the VM still hangs with same messages about unhandled interrupt.

As a side note, I have also a nightly on an USB key which is booting without hanging. Perhaps is it a VM driver or configuration problem?

In fact, the message could be about real interrupts not MSI ones. I was looking at syslog and I think that I found out why interrupts above 15 are not handled. It seems that APICs are not working and PIC mode only manages up to 15 interrupts. Now the question is: Why APIC failed?

found io-apic with address 0xfec00000, global interrupt base 0, apic-id 0
mapping io-apic 0 at physical address 0xfec00000
io-apic 0 has range 0-23, 24 entries, version 0x00170011, apic-id 0
setting ACPI interrupt model to APIC
failed to put ACPI into APIC interrupt model, ignoring
IRQ routing preparation failed, not configuring io-apics
setting ACPI interrupt model to PIC
setting up x2apic for CPU 1: apic id 1, version 327700

Reverting XHCI MSI-X patch fix infinite reset problem for me. But even with MSI-X patch most USB devices are working fine.

The same problem for me, fall back to legacy PIC:

KERN: ACPI: Enabled 7 GPEs in block 00 to 1F
KERN: found io-apic with address 0xfec00000, global interrupt base 0, apic-id 13
KERN: mapping io-apic 0 at physical address 0xfec00000

KERN: mapping io-apic 1 at physical address 0xfec01000

Please retest after hrev57045.

After updating to hrev57051 system boots. Thank you

Thanks for testing! I guess there is some problem in our MSI-X implementation. We should investigate that later, probably.
