System: NetBSD sinus 2.0_BETA NetBSD 2.0_BETA (GENERIC) #6: Thu Jul 1 10:14:49 CEST 2004 ignatios@sinus:/usr/local/src/cur/oi/sys/arch/i386/compile/GENERIC i386
Architecture: i386
Machine: i386
>Description:
	A 3c990B card is plugged into this machine's PCI bus. 
After adding the txp driver to the configuration, it is detected, but
initialization fails with

txp0 at pci0 dev 9 function 0: 3Com 3c990B 10/100 Ethernet with 3XP
txp0: interrupting at irq 5
: not waiting for boot

The last message is output by the firmware download routine when it 
doesn't detect some bit going active, and ...attach() fails.

However, this happens after pci_intr_establish(), so later at
interupt enable time, the kernel crashes in txp_intr().

>How-To-Repeat:
add:
	txp* at pci? ...

config, make depend, make, make install, reboot

>Fix:
	Fix not known.
	Workarounds:
	don't use that card	or
	don't configure it	or
	disestablish interupt on attach() failure,
	like in sys/dev/pci/if_txp.c 1.7.
