Powered USB 3.0 hub causes 0x50 dump_ntoskrn8.sys BSOD?

[Damnation]

Hi @Mov AX, 0xDEAD

On my new AMD B550 build I've come across a scenario where if I have a Powered USB 3.0 hub connected at boot, it causes a 0x50 dump_ntoskrn8.sys BSOD before reaching the desktop.

Would you be willing to help me debug this?

If so, can I have the realtek version of your KDNET to help with debugging this?

Hi @Damnation

dump_ntoskrn8.sys is auto-copy of ntoskrn8.sys linked to storage driver for saving crashdump

storage driver also has copy like dump_iastor.sys, if storage driver is scsi, dump_storport.sys also will be created, this is how windows create independed crashdump driver stack

1) try to fully disable crashdumps in windows control panel

2) if crashdump saved on disk, analyze it in windbg

3) maybe there is some conflict between ntoskrn8.sys and  dump_ntoskrn8.sys, local variables or some similar,   need crashdump or windbg live session !analyze log

4) KDNET is independ of current network driver, rename realtek's kd_02_10ec.dll to kdstub.dll/kdnet10.dll

OK, so I copy and rename kd_02_10ec.dll to kdstub.dll/kdnet10.dll from windows 10 32bit over to my XP install.

Do I need to do any other hex edits to these files for them to work correctly? or they should just work?

[Damnation]

I've discovered a workaround, I can boot into XP if I connect the hub to one of the 2 USB 2.0 ports next to the 2.5gbe ethernet port.

not the most ideal solution, but it's something.

I'd still prefer to find the cause of this BSOD though.

So I'm assuming I don't need to hex edit kd_02_10ec.dll at all? - just rename to kdnet10.dll?

and I get kdstub.dll off of your github?

@Dietmar

If you are able to do so, can you purchase a powered 10-port USB 3.0 hub like this one - https://www.ple.com.au/Products/626733/ALOGIC-Plus-10-Port-USB-30-Powered-Hub-With-Charging

and test if you get BSODs in XP with it?

Yes, you get kdnet v10

I ended up taking the easy way out and got a different USB 3.0 hub that worked with no BSOD

 

this one worked without BSOD -

this one gave the BSOD -

edit:

I still have the problematic hub in my possession so if you want me to go ahead and debug with it anyway, just say so.
