AHA-2940 o/f Ultra support

AHA-2940 o/f Ultra support

[John Adamson]

I have an Ultra 5 with a AHA-2940 o/f scsi card and
when Linux/Ultra is tring to probe devices it gets
stuck looking at the 2940.

Any ideas?  I am running 128mb ram with the latest OBP.

Thanks for your time.

Can you please be more specific on how it gets stuck, what messages does it
print, what kernel are you running, etc.? It should work just fine.

Cheers,

   Best regards,

I have such an Adaptec card here, I will test it and see if I can
reproduce your problem.  If yes, then I will fix it for you.

I believe this to be fixed with current kernels.  The bug was
introduced in 2.1.12[56] and fixed in 2.1.128

All problems were solved! 
Our linux box is running properly.

Thanks for the good support.
