I checked BIOS's log found the fault from the device, I changed "PCI-E Payload
Size"
from 256(default) to 128, now the device works.
I compared lspci output found Address for data of MSI Capabilities's be changed:
Old:
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Address: 00000000fee21000 Data: 40cb
New:
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Address: 00000000fee24000 Data: 405c
Mostly like it's a BIOS bug? please comments.
Thanks,
Joe
