FreeBSD 10.3 - nvme regression

[Borja Marcos]

Hello,

I am trying a SuperMicro server with NVME disks. The system boots FreeBSD 10.2, panics when booting FreeBSD 10.3.

It was compiled on March 7th and Revision 296191 is included.

On 10.3 it’s crashing right after this line:

nvme9: <DC P3500 SSD [2.5" SFF]> mem 0xfba10000-0xfba13fff irq 59 at device 0.0 on pci134

with a panic. 

panic: couldn’t find an APIC vector for IRQ 59.

cpuid = 0
The backtrace is (sorry, copying from a screen video)

#0 kdb_backtrace=0x60
#1 vpanic+0x126
#2 panic+0x43
#3 ioapic_disable_intr+0
#4 intr_add_handler+0xfb
#5 nexus_setup_inter+0x8a
#6 pci_setup_intr+0x33
#7 pci_setup_intr+0x33
#8 bus_setup_intr+0xac
#9 nvme_ctrlr_configure_intx+0x88
#10 nvme_ctrlr_construct+0x407
#11 nvme_attach+0x20
#12 device_attach+0x43d
#13 bus_generic_attach+0x2d
#14 acpi_pci_attach+0x15c
#15 device_attach+0x43d
#16 bus_generic_attach+0x2d
#17 acpi_pcib_attach+0x22c

It said “Uptime 1s” and did a cold reboot.





dmesg.boot from 10.2 (the system in installed on a memory stick).
