Laptop specs HP Zbook Firefly G10 A=20 Ryzen 7 7840 HS Wikingoo Q1L box with JHL6340, also bought and tried Wikingoo P1-60W-M with JHL7440 told by manufacturer, but lspci names it JHL7540.

Without passtrough and Nvidia driver on host system there are still lots of BadDLLP errors, but I haven't seen a crash. I tried pcie_aspm=3Doff with those boxes, but they are not initialized in t= hat case with hotplug and in coldboot case, Intel based system has same behavio= ur. pcie_aspm=3Dforce causes some additional errors on PCIe bus. Possible workaround for me to get a stable system with passtrough is to use pci=3Dnommconf, but this causes graphical glitches on host GPU in 3D render= ing case. --=20 You may reply to this email to add a comment.
