Hello. I entered a problem with double decreasing module reference counter where it become "negative", here is the usage scenario: # modprobe at91_ide # modprobe ide_gd_mod # lsmod Module Size Used by Not tainted ide_gd_mod 22948 0 at91_ide 4672 0 ide_core 77020 2 ide_gd_mod,at91_ide # rmmod ide_gd_mod # lsmod Module Size Used by Not tainted at91_ide 4672 4294967295 ide_core 77020 1 at91_ide Note when I first remove at91_ide module and then ide_gd_mod everyting is ok. I tired to debug issue and I did not found any suspicious in at91_ide. I think probable reason is double free in ide-gd.c . Here is patch with workaround (or maybe it is a real fix, but I'm not sure): diff --git a/drivers/ide/ide-gd.c b/drivers/ide/ide-gd.c index 7857b20..31ae04e 100644 --- a/drivers/ide/ide-gd.c +++ b/drivers/ide/ide-gd.c @@ -70,8 +70,6 @@ static void ide_gd_remove(ide_drive_t *drive) del_gendisk(g); drive->disk_ops->flush(drive); - - ide_disk_put(idkp); } static void ide_disk_release(struct kref *kref) If this patch is ok, maybe similar things need to be done also in ide-cd and perhaps other device type modules.
