Recently bought notebook HP 245 G6, as there is no optical drive, 1st and 2nd stage were performed from Qemu VM using a linux live usb, so ReactOS could be installed at hard disk.
3rd stage (first boot) starts well, showing some new hardware wizards for new devices (mostly ACPI controllers), but when the system loads the multimedia devices, it break the debugger and shows a prompt.
Doing a backtrace the Eip points to HDAudBus.sys (drivers/wdm/audio/hdaudbus/fdo.cpp:674) (HDA_FDOQueryBusRelations)
The line 674 is
I think found the bug
On debug log says:
this is key to find the bug, in the file there is a loop 2 lines below:
then there are 2 DPRINTs that repeats a lot of times
and so on 254 times!
looking after at dmesg, I found that the loop stops at 509 and then breaks the debugger, maybe these are the clues to find the guilty line!
