[Xen-users] gplpv 0.9.11-pre10 BSODs

[Denis Cardon <denis.cardon@xxxxxxxxxxxxxxxxxxxxxx>]

Hi everyone,

first I would like to thank James for the incredible works he is doing 
on the gplpv driver. I've been following the developpement for sometime 
with hard time installing and many BSODs. Now it installs like a charm 
(just press next a few time then reboot). No more little exclamation 
mark in the device manager, quick boot, good performance. Well we are 
getting close to a release!
I stress tested it during a few days and performance were ok. I have 
noticed that it works very poorly when using weird block size, but well, 
it is more than enough for normal use anyway.
So here is my issue : since it was performing ok, I wanted to give it a 
try on a non mission critical app (a few users rdesktoping on a ms 
access front end connecting through odbc to a postgres database). 
Performance are ok and user experience is quite positive.
However about once per day, I get a BSOD that not only freeze the 
windows domU, but also make the dom0 unusable (ie if I try to xm create 
it just hang). The BSOD says (French localised screenshot attached) :
DRIVER_IRQL_NOT_LESS_OR_EQUAL

*** STOP : 0x000000D1 (0x00CA0B2C,0x000000FF,0x00000001,0x808877FA)

I have not found a scenario for reproducing this error, actually it just 
happen sometime in the day. It is not load related because the stress 
test where much heavier on ressources and never produced a BSOD.
Is there any config file parameters that I should be carefull about ? (I 
already removed the ioemu flag from the network card). Any advice or 
hint to get this Windows behaving nicely?
Cheers,

Denis
