Reboot hang

Reboot hang

[kriko]

I have a problem that I cannot solve by myself.

I experience hangs on reboot. Precisely hang occurs when I reboot from  
linux.
Bios show up its screen normally, but after it is done initializing  
devices it wont start booting from them (boot prio: dvd-rom, hd).
It just sits there on summary screen with blinking cursor (at this point  
normally a message appears up like booting from CD/DVD).
The only solution is to do a reboot (press ctrl+alt+del - it does respond  
to that) or to do a hard reset.
This doesn't happen if I shut down the system and then boot it up, or if I  
do a reset from win.

I already tried to boot with apm=off, but it doesn't help, my boot  
parameters are:
---
title openSUSE 10.2 - 2.6.22-custom
     root (hd0,0)
     kernel /boot/vmlinuz-2.6.22 root=/dev/sda1 vga=0x31A resume=/dev/sdb1  
splash=verbose showopts elevator=cfq
     initrd /boot/initrd-2.6.22
---

Bios is up-to-date. I tried reseting bios (and clearing cmos), but it  
doesn't solve the problem.

Here I included lsmod, dmesg and config:

Does it matter at all if you add "reboot=b" (other options w, c, h) as a 
comand line parameter?

None of that parameters worked for me. It seems they do have some effects  
(judging by bios information screen), but they don't fix the problem.
I hope you understood where exactly it hangs (I don't know how is this  
screen called), so here is a quick shot of screen:

After "Verifying DMI Pool data" message it should start booting, but it  
doesn't.

Shame.

"Summary screen" will do, but yes, I understood. Perhaps your BIOS isn't 
fond of the state the Linux drivers leaves your DVD-ROM at. Judging by your 
"nv_pata", you are probebly usiing the pata (pata_amd) driver, not the old 
IDE driver?

Does it boot through if you disable booting from the DVD-ROM?

Mentioning the dvd-rom state, it comes to my mind, when rebooting from  
win, the dvd rom will close tray and  / or LED will blink on reboot.
None of that happens if I reboot from linux, so it could be a driver  
problem. I see that I have both (old and new enable in kernel), I don't  
know which is being used,
but I'll recompile kernel with just one driver and retest.

Seems a fairly safe assumption that the Linux driver leaves your DVD-ROM in 
a peculiar state then. If you have both drivers compiled in, I believe the 
new PATA driver will "win" (judging by the number of people that lost their 
drives on hda...) so I've added its author to the CC.

Repeating information from your first post:

   Gigabyte gak8nsp (nforce 3)

   NEC DVD-RW@nv_pata
   1x 80 GB WD@nv_sata, 1x 250 GB WD@nv_sata , IBM (20GB) @ nv_pata

Machine hangs at summary screen where it would be trying a boot from DVD 
normally on cold boot, or reboot from Windows. reboot=b doesn't help.

Sorted out, built 2 kernels, one with old driver, other with only new  
driver. The one with old driver hangs (it could be because  
BLK_DEV_OFFBOARD was enabled?),
using only new drivers works fine.

Thanks for all your help.

As far as I'm aware it shouldn't, but ...

... oh well. I suppose it's not really worth it to try and debug that. Cheers.

I just want to add that my DVD drive is not detected when using new  
driver. So back to old one....

You shouldn't have dropped Alan from CC then... pata_amd, right?

Sorry, yes its pata_amd.

IBM drive is on Primary master (detected as /dev/sdc)
DVD-ROM is on Secondary master (not detected)

It's probably a timing issue (and might be related to why the old driver 
makes the BIOS hang at reboot) but pata_amd should I believe be one of the 
best tested pata drivers. Using it myself as well, on amd756. I haven't 
observed any problems with (a few) various CD/DVD drives attached and am not 
actually sure how to go about debugging the thing -- over to Alan.

The DVD-ROM is jumpered for master? Or for cable-select and using the master 
cable-slot? Using an 80-ribbon cable for it?

Rene.

It is jumpered as master and connected with first cable-slot.
Cable itself? I don't know, it was supplied with motherboard, though it  
has one pin disabled in middle of connector.
