Description Stefan Fleiter 2003-10-30 09:12:55 UTC
Distribution: Debian unstable
Hardware Environment: ASUS P2L97 (LX-Chipset), P22 333

Problem Description:
First I have to say, taht I searched throuh the oether bug reports and that I am
quite sure that my .config is right.

To the problem:
I built a kernel from source and wanted to boot it, but nothing is printed on
the screen after the boot command of grub, if I copy a 2.4-kernel image at the
same location it boots fine.

.config for kernel that does not uncompress
Comment 2 Martin J. Bligh 2003-10-30 09:31:04 UTC
Try the early printk stuff to see if you get anything. Be sure to turn it on ;-)

ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/patches/2.6.0-test8/2.6.0-test8-mjb1/100-early_printk
Comment 3 Stefan Fleiter 2003-10-31 03:11:37 UTC
Did patch, configure, recompile and set boot-param, but no change.
Any other idea?
Comment 4 Stefan Fleiter 2003-11-04 14:51:34 UTC
Invested a lot of work:
Kernel 2.5.67-bk5 still works.
Kernel 2.5.67-bk6 shows the symptom described above.

patch-2.5.67-bk5-bk6 is quite big, but also has a lot
of architecture specific stuff.

Maybe someone familiar with kernel-hacking could have a look,
I would try suggested patches.

ultra minimal config
Comment 7 Stefan Fleiter 2003-12-15 02:38:40 UTC
So you don't ask for additional info but close this bug report because of
insufficient data?
I spend many hours tracking the bug down to the patch 2.5.67-bk5-bk6.bz2 and you
tell me I gave not enough data?

What do you need to know?
What patch/version should I test?
Comment 8 Zwane Mwaikambo 2003-12-15 05:17:29 UTC
I did require additional info, that's why i posted the 'ultra minimal' config,
could you try the latest kernel with that configuration? It's unlikely to boot
all the way but getting to mounting root will suffice.
Comment 9 Stefan Fleiter 2003-12-15 11:45:26 UTC
You did *not* tell me to test the minimal config.
How should I know it wasn't for your testing.
Will do it as I've time.
Comment 10 Zwane Mwaikambo 2003-12-15 11:52:03 UTC
My apologies then, it was my incorrect assumption. Thanks for testing.
Comment 11 Stefan Fleiter 2003-12-15 13:37:57 UTC
No problems.
I'm glad there is somebody interested in my kernel problems!

[Kernel test11]
Your ultra minimal config works, it can't boot because my root disk
is on a SCSI disk.
I'll try to find the config option causing the lockup/hang/crash/whatever.

I'm compiling your config with SCSI added at the moment.
Comment 12 Stefan Fleiter 2003-12-15 14:49:46 UTC
I was right, adding SCSI, i.e.

CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y
CONFIG_BLK_DEV_SD=y
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_CMDS_PER_DEVICE=32
CONFIG_AIC7XXX_RESET_DELAY_MS=15000
CONFIG_AIC7XXX_DEBUG_ENABLE=y
CONFIG_AIC7XXX_DEBUG_MASK=0
CONFIG_AIC7XXX_REG_PRETTY_PRINT=y

makes the kernel hang at boot time without any output,
earlyprintk does not work in this situation.

Could this be related to
http://www.ussg.iu.edu/hypermail/linux/kernel/0310.1/1523.html
?
It is a UP-System and preempt is not set.

So which SCSI-specififc part of patch-2.5.67-bk5-bk6
could make this happen?
Comment 13 Zwane Mwaikambo 2003-12-15 16:26:11 UTC
Thanks for narrowing it down so quickly! i have a Dell 410 with a similar
controller, does aic7xxx_old work for you? Can you just to play it safe, disable
CONFIG_PREEMPT? Another thing to check for is your final kernel image size
because the SCSI code doesn't get initialised until much later after boot so you
would at least see console output. `size vmlinux` and ls -l arch/i386/boot/bzImage.
Comment 14 Zwane Mwaikambo 2003-12-15 16:29:11 UTC
My mistake, ignore the comment about CONFIG_PREEMPT. Also i don't think the
problem in the URL and yours are related.
Comment 15 Stefan Fleiter 2003-12-17 16:03:31 UTC
Ok it is *not SCSI-related.
Was a bug in mybuild scripts which did not detec a build-error and
copied a broken bzImage.

The config option leading to the kernel not booting is
CONFIG_VIDEO_SELECT=y.

I checked sveral .config-files which did not produce a working kernel for me,
all worked after setting CONFIG_VIDEO_SELECT=n.

So again ( :-) ):
Which part of patch-2.5.67-bk5-bk6 could cause this?

Thanks for your attention.
Comment 16 Zwane Mwaikambo 2003-12-18 06:04:25 UTC
What does your kernel command line look like? vga=ask?
Comment 17 Stefan Fleiter 2003-12-18 15:45:06 UTC

disable store_edid

Could you test the following patch with CONFIG_VIDEO_SELECT=y
Comment 19 Zwane Mwaikambo 2003-12-19 03:54:36 UTC
For future reference, the preceding patch was to disable the following changeset;
ChangeSet 1.1035 2003/04/14 12:14:31 torvalds@home.transmeta.com
  Store EDID only when CONFIG_VIDEO_SELECT is set and edid
  function actually exists.

But the real changeset to watch out for would be;
ChangeSet 1.1006 2003/04/10 11:20:26 jsimmons@kozmo.(none)
  [FBDEV] EDID support from OpenFirmware on PPC platoforms and from the BIOS on
intel platforms.

Hello Stefan, sorry for the long delay in following up to you. Do you experience
the same problem (without the patch) in current 2.6 kernels?
Comment 24 Stefan Fleiter 2004-02-12 00:22:40 UTC
Yes, it still happens with kernel 2.6.3-rc2.

This bug certainly hasn't been fixed, it requires specific video hardware but is
still out there. Unless someone points me towards a changelog, we should at
least leave it open.
Comment 29 Tobias H. 2007-01-31 06:14:18 UTC
I verify the bug, being still open.

graphics card: Chips & Technologies 65548 VESA VBE 1.2

Configuration
CONFIG_VIDEO_SELECT=Y
CONFIG_FIRMWARE_EDID=Y

kernel <= 2.6.17.14 : works
kernel >2.6.18 : crashes hanging right before uncompressing kernel.

The first patch suggested here
http://bugme.osdl.org/attachment.cgi?id=1698&action=view
works fine.

Actually I have not tried this, since

CONFIG_FIRMWARE_EDID=N

also disables the store_edid [at least during booting the kernel. I do not know
about other side effects]. But not at the same time disabling video select
(which I consider still useful).

With this altered configuration even kernel 2.6.19.2 boots fine.

This diff is from inside the store_edid subroutine. Basically it's the check to
see if 0x4f15 is available at all. It's introduced by the chancesets Zwane
Mwaikambo mentioned.

It's interesting, since this check crashes my machine, but the actual call
0x4f15 with bx=$0x01 does not crash my machine. The latter one is performed by
2.6.17.x

ct4554x BIOS Manual
http://www.asiliant.com/pdf/oc54x.pdf
states offering only functions 0x4f00 - 0x4f10. I assume they did not implement
the check for 0x4f15.

http://www.vesa.org/public/VBE/vbe3.pdf
Appendix 3, page 82
states "Added Supplemental Functions definition and defined Supplemental
Functions 10-16h". Therefore the actual check for 0x4f15 is NOT required by VBE 1.2.

Suggested fixes:

Option 1: Add a note to the description text of "CONFIG_FIRMWARE_EDID" saying
not to be used in <=VBE 1.2

Option 2: If CONFIG_FIRMWARE_EDID provides in other source codes that I have not
looked into any useful functionality even with VBE 1.2, than maybe dynamically
check VBE version before trying to call 0x4f15.

No EDID/DDC on VBE12

Updated for i386 & x86_64
Comment 34 Tobias H. 2007-04-29 03:31:02 UTC
Thanks to Zwane a fix has been integrated in vanilla kernel 2.6.21:

-- 8< --

    [PATCH] x86: Don't probe for DDC on VBE1.2
    
    VBE1.2 doesn't support function 15h (DDC) resulting in a 'hang' whilst
    uncompressing kernel with some video cards. Make sure we check VBE version
    before fiddling around with DDC.
    Tested on;
    
    i386, Chips & Technologies 65548 VESA VBE 1.2
    CONFIG_VIDEO_SELECT=Y
    CONFIG_FIRMWARE_EDID=Y
    
    Untested on x86_64.
