Hello,
I'm running 2.6.0-test1-ac3 on my sis-based laptop, and I've some problems with the sis 900 networking card: in a low-bandwith usage (like a ssh to another computer, or a copy from another computer with a 10Mbps card), I get some network freezes, and after a few seconds it starts again (with the following messages in the syslog):
Aug 3 11:55:13 kesto kernel: eth0: Media Link Off Aug 3 11:55:22 kesto kernel: NETDEV WATCHDOG: eth0: transmit timed out Aug 3 11:55:22 kesto kernel: eth0: Transmit timeout, status 00000004 00000000 Aug 3 11:55:23 kesto kernel: eth0: Media Link On 100mbps full-duplex
When I copy files to another 100 Mbps laptop (with a cross-cable), after a short while the network stops completly to work, and I cannot even rmmod sis900 (device or ressource busy).
If you want the /proc/pci entry for the network card:
Bus 0, device 1, function 1: Ethernet controller: Silicon Integrated S SiS900 10/100 Ethern (rev 130). IRQ 10. Master Capable. Latency=128. Min Gnt=52.Max Lat=11. I/O at 0x3200 [0x32ff]. Non-prefetchable 32 bit memory at 0x44000000 [0x44000fff].
I've enabled preempt and local APIC in my kernel configuration, but I used to patch my 2.4 kernels with preempt before switching to 2.6 and I never had any network-related problem.
As a side-node, I can tell you that when we (a friend and I) ported the sis900 driver to GNU Mach, we had to add a delay loop (I know, it's ugly, but it's just a quick-and-dirty patch while waiting for the OSKit-based GNU Mach) in the sis900_start_xmit function. With no delay at all the driver stopped to work after one packet has been transmitted, with a small delay it worked for low-bandwidth program (say, a "ping 192.168.1.1") but not for a file transfert, I had to add a bigger one to make it work fine.
I'm available if you need additional informations.
