Hi After resolving http://bugzilla.kernel.org/show_bug.cgi?id=7481 I was thinking about possibilities how to prevent such bugs with testing. Usually just few insmods and rmmods show, whether the initialization and cleanup code of module is ok or not. I created a script which do the automatic job of finding all modules and inserting/removing them (see attachment). On my Lifebook E8110, kernel 2.6.18.2, the following modules were problematic: arptable_filter pktgen rfcomm rpcsec_gss_krb5 sdhci xt_NFQUEUE Kernel logs usually say "BUG: unable to handle kernel paging request at virtual address ..." or "BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000". When trying knoppix 5.0.1, my script causes total freeze quickly. Is it worth to report each buggy module to bugzilla? Reproducing is quite simple, effects common. People just usually don't use many insmod-s & rmmod-s in normal life... Palo
