While loading X, I get this oops. The weird thing is that I don't use
framebuffer. I compiled with gcc 3.2.2 but the code generated looks weird.
Virgin gcc 3.2.2 on a pentium III.
Oops, followed by my unskilled ruminations:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:

This output looks somewhat bogus to me as it appears to try to dereference
'module' before it has been tested for zero or not:
static inline int try_module_get(struct module *module)
{
c0275a08: 8b 86 94 01 00 00 mov 0x194(%esi),%eax
int ret = 1;
c0275a0e: ba 01 00 00 00 mov $0x1,%edx
c0275a13: 8b 00 mov (%eax),%eax
if (module) {
c0275a15: 85 c0 test %eax,%eax
c0275a17: 74 0b je c0275a24 <fb_open+0x44>
c0275a19: 83 38 02 cmpl $0x2,(%eax)
c0275a1c: 74 6a je c0275a88 <fb_open+0xa8>
which is called from fb_open:
static int
fb_open(struct inode *inode, struct file *file)
{
int fbidx = minor(inode->i_rdev);
struct fb_info *info;
int res = 0;
#ifdef CONFIG_KMOD
if (!(info = registered_fb[fbidx]))
try_to_load(fbidx);
#endif /* CONFIG_KMOD */
if (!(info = registered_fb[fbidx]))
return -ENODEV;
if (!try_module_get(info->fbops->owner))
return -ENODEV;
if (info->fbops->fb_open) {
res = info->fbops->fb_open(info,1);
if (res)
module_put(info->fbops->owner);
}
return res;
}
This suddenly appeared in 2.5.66, 2.5.65 works flawlessly with the same
compiler.

You don't use framebuffer? Can you send me your config.

First I ran it with
# CONFIG_FRAMEBUFFER_CONSOLE is not set
and later with
CONFIG_FRAMEBUFFER_CONSOLE=y
and it doesn't make a difference.
Relevant bit from XF86Config-4:
Section "Device"
Identifier "SiS blah"
Driver "sis"
Option "UseFBDev" "false"
EndSection
This is the sis driver from http://www.winischhofer.net/linuxsis630.shtml

Ok, I've found the bug, it is in fb_open() in drivers/video/fbmem.c, it
needs this addition:
if(fbidx >= FB_MAX)
return -ENODEV;
Without it, large minor numbers result in access beyond the end of
registered_fb.
On Debian, ls /dev/fb[67] results in:
crw--w--w- 1 root tty 29, 192 Nov 30 2000 /dev/fb6
crw--w--w- 1 root tty 29, 224 Nov 30 2000 /dev/fb7
On Red Hat this is:
crw------- 1 root root 29, 7 Apr 11 2002 /dev/fb7
crw------- 1 root root 29, 8 Apr 11 2002 /dev/fb8
Which explains why many don't see this bug.
Regards,
bert

Documentation/devices.txt (at least in 2.5.64) states that those
devices should be fully supported:
For backwards compatibility {2.6} the following
progression is also handled by current kernels:
0 = /dev/fb0
32 = /dev/fb1
...
224 = /dev/fb7
So perhaps the patch should look something like:
if (fbidx >= FB_MAX) {
/* Support older device minor numbering */
if (fbidx%32!=0)
return -ENODEV;
else
fbidx/=32;
/* Check if it is still too large */
if (fbidx >= FB_MAX)
return -ENODEV;
}

Ah. That explains it. I will apply the fix.

That is no longer true. The fb nodes should be recreated. I fixed the docs
in devices.txt

Fine with me, however someone might want to look at the device numbering
that the various Linux distros are using at this moment. I know Debian
is using the old numbering and I just filed a bugreport to get that
updated. I do expect a fair amount of people will run into this when
they upgrade to 2.5/2.6 kernels.

Only if they have more than one video card which is pretty small number.

Note that Debian seems to use the old numbering that was obsoleted in 2.4.0.

Since when is that a relevant factor in breaking backwards
compatibility?

All G400 and newer matroxfb users have dualhead system, so number is
not that small. Definitely not from my point of view ;-)
Problem is that Debian unstable still supports 2.2.x kernels
(kernel-image-2.2.20... & 2.2.22) and this version supports only 0/32/64/...
minors.
So if you filled bug against makedev, you have to fill bug against 2.2.x
kernels too - either remove them or patch them, as otherwise updated
makedev has to conflict with kernels << 2.4.0.

That's fine for new installs, but people never run MAKEDEV when
upgrading their kernel.
