There was a problem that got fixed around 2.4.6-preSomething. Without a
ksymoops, nobody will be able to verify it, but assuming you don't want
to try something more recent than 2.4.5 (which I guarantee has this bug
I'm thinking of within stock kernels), you can manually edit a file and
test this. If you go to your kernel source, file fs/block_dev.c, find
function ioctl_by_bdev (near line 596). Within that function, you'll
see:
inode_fake.i_rdev=rdev;
Immediately after this, also add:
inode_fake.i_bdev=bdev;
A couple of lines before that, something else that wouldn't hurt is to
initialize the struct. You can change the line that appears like this:
struct inode inode_fake;
Such that it becomes this instead:
struct inode inode_fake = { 0 };
The new function will look like this:
int ioctl_by_bdev(struct block_device *bdev, unsigned cmd, unsigned long
arg)
{
kdev_t rdev = to_kdev_t(bdev->bd_dev);
struct inode inode_fake = { 0 };
int res;
mm_segment_t old_fs = get_fs();
if (!bdev->bd_op->ioctl)
return -EINVAL;
inode_fake.i_rdev=rdev;
inode_fake.i_bdev=bdev;
init_waitqueue_head(&inode_fake.i_wait);
set_fs(KERNEL_DS);
res = bdev->bd_op->ioctl(&inode_fake, NULL, cmd, arg);
set_fs(old_fs);
return res;
}
Be sure to do a make mrproper, config it, and then do a completely new
build. If that fixes it, then you can bet 2.4.6+ won't have this
problem.
