Hi, all
Sorry for troubling you.
We are developing msix feature on our product, unfortunately it will
lead kernel to crash
on a server PC whose cpu is Intel(R) Xeon(R) CPU E5645, and we are
sure that our driver is good
on common personal PC.
A piece code in our driver like that:
for (i = 0; i < msix_num; i++) {
msix = &pcie->msix_entries[i];
msix->entry = i;
}
ret = pci_enable_msix(XX);
for (i = 0; i < msix_num; i++) {
msix = &pcie->msix_entries[i];
ret = request_irq(msix->vector, XX);
}
BTW, the kernel crash info is as follows:
[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 32993
[Hardware Error]: APEI generic hardware error status
[Hardware Error]: severity: 1, fatal
[Hardware Error]: section: 0, severity: 1, fatal

[Hardware Error]: secondary_bus: 0x00
[Hardware Error]: vendor_id: 0x1c5f, device_id: 0x0530

Do I miss something important?? Can anybody give me some hints?
