Hi LQ, it's been a while.

I recently purchased a laptop with a SiS chipset. I installed Ubuntu 7.10 (Gutsy) onto it, and got mostly everything going, except for accelerated OpenGL... and this quirk with the SiS 191 GbE network controller.
It is recognized correctly by the 'sis190' kernel module which ships with Ubuntu, and an 'eth0' device becomes present. I configured my ADSL connection with pppoeconf, then fired it up... it connects, gives me an IP address, can resolve DNS, and is able to ping. However, if I go anywhere (except for Google, don't ask me why) with the browser it always times out. I'm using Windows XP to post this because of this problem.
Something that caught my attention is that if I do 'ifconfig eth0' the bottom line shows "Interrupt: 21 Base address: 0xdead". This "0xdead" might be a sign of trouble, but... how come the PPPoE client is able to connect, give me an IP address and even ping?

Thanks in advance.

PS: Because of CPU frequency scaling the kernel has a problem with the TSC (the CPU is a Celeron M 530) and I had to pass "clocksource=jiffies" to the kernel command line to avoid timing problems. I don't think so, but could this have a connection to the problem I describe above (incorrectly-calculated timeouts, maybe)...?

It just worked, out of nowhere. I didn't do anything. I'm posting this through my Ubuntu install now. The address=0xdead persists though, it may as well be harmless...?
It may be that this problem is intermittent (I think I've ascertained it's not from my service provider, as I'm always able to connect when using Windows) though, I'll post again in case I have trouble again, with more details if possible.

Once again, thanks in advance.

A kernel upgrade seems to have solved the problem. I compiled and installed the latest kernel (2.6.25-RC7) from http://www.kernel.org, have rebooted three times already and connection is working fine. Since upgrading the kernel seems to have solved it, it's likely that the upcoming Ubuntu Hardy will not have this problem.

I'v got the same problem with the bottom line of ifconfig:
"Interrupt: 21 Base address: 0xdead"

It's server edition 8.04 and seems the problems goes on.

What do you suggest to do?

Thanks,

Yiannis
