[vortex] reproducable pci bus errors (905c-tx, target abort)

Tue, 14 Aug 2001 00:49:43 +0200

hi,

i've got trouble with a 3c905C-TX in a dataexperts exp8049 mobo, 486/66, equipped with two more NICs: one 905B-FX and one 509B (ISA). the box is running suse linux 7.0 (kernel 2.4.0), 3c59x.c:LK1.1.12 is inserted as module.

whenever i route traffic over the 3c905C-TX (eth1 in my configuration), it will break with a

  PCI bus error, bus status 40000020

after less than a megabyte. when it breaks, its LINK-LED on the switch will turn off. the LED turns on when i "ifconfig eth1 down" and turns off again when i "ifconfig eth1 up". the only way to get things going is to remove and reinsert 3c59x.

the 3c905B-FX and 3c509B work flawlessly, the error is bound to the 905C. with suse 6.4/kernel 2.2.14 however, the box would hang as soon as the 905C went down (no response to keystrokes).

i put the appropriate output from lspci, dmesg etc. at the bottom. i found a mail by andrew morton in the linux-kernel mailinglist, date 6-dec-2000, subject "horrible hack from hell called a20", where a driver patch is suggested to provide more info about the PCI error. i would happily apply such a patch to my box if that could yield useful info.

thanks for any help.

this is found about 20 times per second after eth1 went down:

and this is the output of lspci -vv (both before and after eth1 broke)
