This may be related to the firewire protocol errors, but when using
kdfiles to transfer a file over a firewire connection, occasionally the
target machine will get stuck in an infinite loop:
[here i’m reloading a graphics driver]
PHMIRROR: DrvDisableDriver called.
LPC[5bc.31c]: Refusing connection from 5bc.740
LPC[6c4.470]: Refusing connection from 6c4.6ec
KD: Accessing ‘D:\funk\Proxy4.new\Build\Debug\phmdisp.dll’
(\SystemRoot\System32\phmdisp.dll)
File size
228K…
(and the .'s keep going forever).
I cannot break into the target at this point. I have to do the following:
- I must unplug the target machine to shut it off
- Reboot the target
- usually unplug and re-plugin the firewire connection just for purely
superstitious reasons - Close down WinDBG on the host
- Wait for the target to boot up far enough that it allows a debugging
connection - Start WinDBG (if I start it before the debugging connection on the
host is available, I’m unable to break into the target until I restart
WinDBG) - Then I must try and break in before the now-corrupted version of the
driver on the target is loaded so that WinDBG can try and transfer a new
copy of the driver over…
Is this a known bug?
