Bug 184821 – >=kernel-2.6.21 hangs on boot at "io scheduler cfg registered (default)" line

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Anton Kuzmin 2007-07-10 11:06:10 UTC]

suspend2-sources and gentoo-sources >= 2.6.21 hangs on boot at "io scheduler cfg registered (default)" line.

There is no kernel panic, the kernel just gets stuck during boot.

I tried acpi=off noacpi with no luck. Tell me how to DEBUG.


Reproducible: Always

Did 2.6.20 work?
Can you please test gentoo-sources-2.6.22?

[Comment 2 Anton Kuzmin 2007-07-11 07:45:29 UTC]

>Did 2.6.20 work?

Yes, it works. It works even if I compile it again. I use suspend2-sources-2.6.20-r6 (r5 worked too).

>Can you please test gentoo-sources-2.6.22?

I have already done it before commiting this bugreport.

kernel config for gentoo-sources-2.6.22

Before building a 2.6.22 kernel I ran 'make oldconfig' and changed just added SOME features.

[Comment 5 Anton Kuzmin 2007-07-11 10:57:05 UTC]

The same thing with linux-image-2.6.22-7-generic in Ubuntu.

[Comment 6 Maarten Bressers (RETIRED) 2007-07-19 22:38:22 UTC]

Please post the .config of the latest working gentoo-sources.

Are you able to get the kernel output during boot to another machine, by using either netconsole or a serial console? For more information about this, read networking/netconsole.txt and serial-console.txt in the /usr/src/linux/Documentation/ directory.

[Comment 7 Daniel Drake (RETIRED) 2007-07-27 02:34:41 UTC]

Please try enabling CONFIG_FIRMWARE_EDID

[Comment 8 Anton Kuzmin 2007-07-27 07:52:20 UTC]

I need a couple of days to get my laptop back. I'll try everything you suggested.

[Comment 10 Anton Kuzmin 2007-08-04 10:51:33 UTC]

Same thing with gento-sources-2.6.22-r2 with config for linux-2.6.20-gentoo-r6 + CONFIG_FIRMWARE_EDID

I don't use any framebuffers.

[Comment 11 Daniel Drake (RETIRED) 2007-08-05 22:22:58 UTC]

Can you test the latest development kernel, currently v2.6.23-rc2?

[Comment 12 Maarten Bressers (RETIRED) 2007-08-21 19:03:28 UTC]

So have you tested the latest development kernel (currently: sys-kernel/vanilla-sources-2.6.23_rc3)?, and if so, what were the results?

Something else you can try: take your working 2.6.20 .config and do a make oldconfig without adding/changing anything yourself (to select the default option just press enter) on your 2.6.22 kernel. If it still doesn't boot, try adding "noapic nolapic" to your kernel command line (in your bootloader config file).

[Comment 13 Daniel Drake (RETIRED) 2007-08-22 13:27:37 UTC]

Please reopen when the latest development kernel has been tested. Also, if you have time, it may be possible to locate the exact commit between 2.6.20 and 2.6.21 which introduced this bug for you (but do confirm that the latest 2.6.23-rc kernel also has the issue). See:
