SiS pci target abort?
Quoted 17 lines
I'm running a linux 2.4.18 kernel on a PC with SiS glue chip:
cubox2.sj.broadcom.com$ lspci
00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0650 (rev 01) 00:01.0 PCI bridge: Silicon Integrated Systems [SiS] 5591/5592 AGP 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 00:02.2 USB Controller: Silicon Integrated Systems [SiS] 7001 (rev 07) 00:02.3 USB Controller: Silicon Integrated Systems [SiS] 7001 (rev 07) 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev d0) 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 PCI +Audio Accelerator (rev a0)
00:03.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 10/100 +Ethernet (rev 90)
00:0f.0 Network controller: BROADCOM Corporation: Unknown device 4301 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS]: Unknown device +6325
Quoted 8 lines
Reading a Broadcom device register which returns a pci target abort will return the last value read, the SiS chip actually cycles thru the last 4 recently read values, instead of returning
0xfffffffflike all other PC system chips I've ever seen. Is this a known SiS chip bug?Thanks much for any info you could provide.

Not much info as I don't have the hardware here to reproduce your config. From your e-mail address I assume you're developing Linux drivers for your network cards or debugging a problem with existing ones. I took the liberty of forwarding your e-mail to the linux-kernel mailing list. If this problem is known there are chances one subscriber is aware of it (there are SiS people around here).
