Sample bugfixes 2.6.24 -> 2.6.25, cb7cd429, 0653136, 08bf11d
Updated by Evgeny Novikov almost 12 years ago
Corresponding plain model 68_1 was successfully implemented. But after fixing #453 and related issues, this model behaves strangely. My local launch demonstrated such the difference for medium regression test set:

while night tests have shown:

That is the first change is the same while the second one is different.

Two times night tests showed the following difference for the given rule:
-driver=kbdrivers--0068-2.6.31.6--test-0068-2.6.31.6-verdict-unsafe-drivers--net--usb--cdc_eem.c.tar.bz2;origin=external;kernel=linux-2.6.31.6;model=68_1;module=drivers/kbdrivers/0068-2.6.31.6/test-0068-2.6.31.6-verdict-unsafe-drivers--net--usb--cdc_eem.c/cdc_eem.ko;main=ldv_main0_sequence_infinite_withcheck_stateful;verdict=unknown;RCV_status=fail;problems=Time_limit +driver=kbdrivers--0068-2.6.31.6--test-0068-2.6.31.6-verdict-unsafe-drivers--net--usb--cdc_eem.c.tar.bz2;origin=external;kernel=linux-2.6.31.6;model=68_1;module=drivers/kbdrivers/0068-2.6.31.6/test-0068-2.6.31.6-verdict-unsafe-drivers--net--usb--cdc_eem.c/cdc_eem.ko;main=ldv_main0_sequence_infinite_withcheck_stateful;verdict=safe -driver=kbdrivers--0068-2.6.31.6--test-0068-2.6.31.6-verdict-unsafe-drivers--input--mouse--bcm5974.c.tar.bz2;origin=external;kernel=linux-2.6.31.6;model=68_1;module=drivers/kbdrivers/0068-2.6.31.6/test-0068-2.6.31.6-verdict-unsafe-drivers--input--mouse--bcm5974.c/bcm5974.ko;main=ldv_main0_sequence_infinite_withcheck_stateful;verdict=safe +driver=kbdrivers--0068-2.6.31.6--test-0068-2.6.31.6-verdict-unsafe-drivers--input--mouse--bcm5974.c.tar.bz2;origin=external;kernel=linux-2.6.31.6;model=68_1;module=drivers/kbdrivers/0068-2.6.31.6/test-0068-2.6.31.6-verdict-unsafe-drivers--input--mouse--bcm5974.c/bcm5974.ko;main=ldv_main0_sequence_infinite_withcheck_stateful;verdict=unknown;RCV_status=fail;problems=Blocks_SAT,Exception
Thus, kbdrivers--0068-2.6.31.6--test-0068-2.6.31.6-verdict-unsafe-drivers--net--usb--cdc_eem.c.tar.bz2 is unstable driver and I'm going to exclude it from general test suite (but one who will take care of this model should understand what happens). To pass night tests I also should apply the second change to the suite...
