Freebsd 5.3 Drivers cause Kernel Panic

[Freedevil]

OSS 3.99.1i oss3991i-freebsd-x86-v5.3-RELEASE.tar.gz used upon running oss-install it detects the cards fine if you run self audio test machine panics and hangs but i was logged into X at that time.

Upon reboot reinstalled them ran soundon

I've just tested SBLive on my 5.3-RELEASE wiith the latest OSS
and no problems here. I'd recommend that you use the "RELEASE"
kernel - make sure that the kernel drivers aren't being loaded.

Is this a dualproc or single proc machine?

BTW, how much memory does you system have?

hey dev

vampire# uname -a
FreeBSD vampire.bloodlust.net 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Sat Nov 6 07:38:35 EST 2004 root@vampire.bloodlust.net:/usr/src/sys/i386/compile/ESCAFLOWNE i386

Single Processor System

No Sound drivers in kernel as you know 5.3 has a new sound.ko module system you can directly load emu10k with kldload.Ii still get the same error with oss drivers

OSS: UNABLE TO ALLOCATE 4096 bytes for a DMA Buffer and the kernel panic message previously posted.

If by RELEASE kernel you mean GENERIC? then no i have built my own kernel.
For furthur clarification you can view my kernel here htttp://unixdaemon.org/ESCAFLOWNE.txt

vampire# cat /boot/loader.conf
linux_load="YES"
nvidia_load="YES"
agp_load="YES"
#snd_emu10k1_load="YES"
hw.ata.atapi_dma=1
hw.ata.ata_dma=1
#bktr_load="YES"

As soon you can see no sound being loaded as far as i know soundconf will not run unless all modules connected to sound are loaded, so i am guessing that is not the problem. I am surprised it worked for you cuz uhh my machine has hung 3 times now with kernel panics.

[Freedevil]

Well i booted kernel.old the GENERIC kernel and the drivers work fine.

Few problems here
a) what does oss need specifically from the kernel
b) Mainly hardware is tuned in my kernel which does not concern sound as far as i know

I am gonna try and fiddle with the settings i guess but do take a look at my kernel cuz i am pretty sure other users migth face this too

[Guest]

Well i had to unhash useless stuff from my kernel cuz i guess i dont have the time or spare machine to test this out at the moment, so i have oss drivers working now. I have 6 speaker logitech set but i cannot hear my front left speaker all other 5 are working. Not sure what to do here any help would be appreciated. by the way its sb live 5.1 card

[Guest]

err nevermind i seemed to have fixed the issue all 6 speakers work now but i'll try and work on the kernel trouble

[Guest]

i've the same problem:
FreeBSD 5.3 with custom kernel -> kernel panic
i hope u find it out whats so important in the GENERIC kernel, and what misses at ours.

Perhaps you should diff between /usr/src/sys/i386/conf/GENERIC and your kernel and see what's different.

Does OSS bomb if you compile the GENERIC kernel (what I mean is if you generate a GENERIC kernel on your machine and reboot and run soundon)?

hey dev the diferences like i pointed there are maninly hardware options like raid scsi etc. Now when i say GNERIC kernel its the 5.3-RELEASE kernel i rebuilt that the one you tested oss on and sure it runs fine. But when i look at my own kernel ESCAFLOWNE and GENERIC the differences are here i dont use raid ro scsi so i have them #'ed out I have picked my own usb and ethernet options. Added firewall suport and dvd bruning thats it!!! The fact that soundon panics by this leaves me baffled.

I really cannot tell you why recompiling your kernel causes the segfault.
The thing I would like you to do is just recompile GENERIC on your
machine and see if the compiled kernel has problems or not.


Send us your kernel config so that we can recompile it on our machines. It (will take time unless you have a paid OSS license key.).

[Freedevil]

YEs i do have a paid license my kernel was posted previously like i said in my previous posts its running fine with GENERIC you can grab a copy of my kernel where oss segfaults http://unixdaemon.org/ESCAFLOWNE.txt <--- feel free to build it and test it

This is the main reason i decided to post it here.

[Freedevil]

Heres the current working kernel for oss http://unixdaemon.org/NEWKERNEL.txt

Heres the diffrence between ESCAFLOWNE where oss kernel panics and NEWKERNEL where it works.

Usless stuff no good to me irrevalant to sound

Benjamin unhash the scsci part and take a look at NEWKERNEL.txt it works fine as far as i can tell SCSI was the option that stopped it from panicking wweird yeah tell me about it its a pain to fsck 300gb hard disks
