Compiled first 2.6 kernel

Elukyz · 06-30-2007, 12:25 PM

Hello,

I just got through with my first successful compilation of a 2.6 kernel (2.6.21.5). Computer boots smoothly, only abnormal messages I have spotted so far are:

Quote:

Jun 29 02:07:02 linuxbox kernel: i810_audio: AC'97 codec 0 Unable to map surround DAC's (or DAC's not p
resent), total channels = 2
Jun 29 02:17:53 linuxbox kernel: i810_audio: drain_dac, dma timeout?
Jun 29 02:17:53 linuxbox kernel: i810_audio: drain_dac, dma timeout?

That was on my first boot but when I rebooted again the "dma timeout" messages went away...Maybe a hiccup in my system? Also, I have a couple questions. While running a 2.4 kernel I had a bunch of modules which dont seem to be there anymore and yet even while they are all missing, my system seems to boot fine and I can even access the internet even though I had to probe for my sis900 adapter at bootup with the 2.4 kernel.

Ike@linuxbox:~$ lsmod

nvidia 3929920 12

There were a bunch more modules there such as my sis900 adapter ( I failed to take a snapshot prior of all modules prior to compiliation). Does the 2.6 kernel see these differently?

Also, at bootup I see my filesystems being fsck-ed. I never saw this during my bootup proccess with the 2.4 kernel and actually dont mind it, but during the check of the root partition it gives me FATAL: module not found but continues on smoothly. I will reboot again once this post is complete to catch what modules these are but will I have to recompile to get that fixed or are there paramenters I can change?

Any input is appreciated, if you would like me to display more info let me know.

Thank you

Ok, I think I have my answer for the module error from looking around...They are not being checked from the filesystem check but the rc.modules is probing for them as modules and cannot find them. I tried to probe fro them as root and failed as well with the FATAL cannot find. These modules include sis900 agpart and ide-scsi. I am thnking another re-compile but if anyone else has any suggestions, I am all ears.

Thank you

1. Did you build them as modules or compile them into the kernel?

2. Did you do "make modules_install" after compiling your kernel?

They were built into the kernel, I rebuilt the kernel, set some option that were built-in to the kernal as modules that looked safe and still get the ide-scsi failure, but from further research I came to find that that is no longer needed as ide-cd has supersceded it, thus commented it out in rc.modules.

New lsmod output....

I still get the "dma is turned off" message when my file systems are being checked at bootup. I tried to set the parm manually but get the error:

Quote:

/dev/hdb5:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Invalid argument
using_dma = 0 (off)

Any ideas??

Thanks

EDIT:::
dma problem solved, used wrong intel chipet when compiling...All is good now, I hope...Thanks
