KDL at boot with SBLive

[biffuz]

Just updated Haiku to hrev25795 (don't remember the previous one), built myself with buildtools, and now it crashes at boot. It seems it has something to do with OSS and the SBLive driver.

You should *not* be using OSS on hardware that Haiku already has a supported driver for.

The current OSS port is not "intelligent" enough to disable itself when Haiku has a built-in driver, and thus it will likely cause conflicts when both drivers try to access the same hardware simultaneously.

Thus, OSS should only be installed and used when absolutely necessary in the event that no native driver exists for your hardware.

[biffuz]

Well, but why this happens only now? It didn't, and I did not change the build config since previous build. Or maybe I should go with a clean install and try again?

[umccullough]

Maybe you just got lucky?

Simply put, there's currently no protection in place to prevent OSS from colliding with the built-in emuxki driver - and thus you shouldn't expect the system to be stable when using both. This has already been explained in the past by mmu_man, and he knows there needs to be a solution in the future.

Tried with a fresh install, no luck. The crash is 100% reproducible. Probably something was wrong with the older one, who knows.

[umccullough]

To verify if it's actually a problem with the built-in emuxki driver in combination with OSS, you could always boot to safe mode console and remove that driver from the system manually.

It's hard to see in the picture, but it looks like the panic is that it has acquired a lock with interrupts disabled.

It might just be a bug in OSS or something?

I tried to delete emuxki driver and OSS still crashes!

Could you try using this newer version ? It should fix several bugs including a nasty too small malloc in my code. ​http://revolf.free.fr/beos/oss-beos-v4.1test-bin.zip

Nothing changed, exactly the same crash.

[mmu_man]

You really sure you removed the native driver ?

Yes :-) I also tried to delete all audio drivers (just in case), but no help.

I also get a kdl when oss is installed. (sblive 5.1 emuxki) At boot it shows:

PANIC: aquire_spinlock: attempt to aquire lock 0x81ecba08 with interrupts enabled

Without oss drivers it loads fine and sound works.

That would be OpenSound conflicting with the native emuxki driver.

Try retesting Haiku with a recent build and if it still isn't working for you please reopen this ticket, and include details of what you tried including Haiku revision number.
