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.
