Ahh. I didn't know that. Well, I begin to see *good* resons to move to
2.4, since I have a bunch of devices running of 4 SCSI channels
doing *lots* of stuff - shame on me, I never checked how the
interrupts got handled.
Well, for the other problem - I don't have it. Only two CPU's here ;-(
I once saw a ES40 on a computer show - let me tell you, the d**n thing
was too heavy to be carried away by me
Anyway, as for the spinlocks getting stuck sometimes in 2.2.x, is this
fixed in 2.4 ( I have checked some of the patches, but by far not all ) ?
Reading Alan Cox' ToDo list in the kernel-mailing list somewhat frightens
However, it is hard to tell, how much of it is Alpha-related, since
Alan is - ahem - somewhat x86-centric for that matter ;-)
Any serious problems so far in practice ? I would like to try out some
of the new things in 2.4...
