Problem Description:
On boot, I'm getting lots of debug-looking messages:

Limiting direct PCI/PCI transfers.

BTW, system later oops in Vortex init, with a vortex_interrupt oops when the 
NIC starts.. maybe its related?

Steps to reproduce:

Comment 1 Burton Windle 2003-04-21 08:22:09 UTC

Looks like the "nobody cared" message comes from arch/i386/kernel/irq.c:228.

Comment 2 Burton Windle 2003-04-21 09:07:36 UTC

According to jgarzik@pobox.com:

Fix already sent to Linus.

Note that we will have lots of bugs like this in 2.5.68-bk1, until we
get the new interrupt handler return value sorted.

With 2.5.68-bk3, I get this on boot:

Comment 4 Burton Windle 2003-04-24 09:06:25 UTC

With 2.5.68-bk5, it looks like this:

Comment 5 Dave Jones 2003-05-04 19:18:23 UTC

Fixed in 2.5.69 ?

Comment 6 Burton Windle 2003-05-05 06:27:11 UTC

Nope, no difference in 2.5.69.
