Yes, let's disable it for all TG3_FLG2_5780_CLASS chips for now until we figure out what's going on. David, Here's the patch if you haven't already made one: [TG3]: Disable TSO by default on 5780 class chips. Disable TSO by default on 5780, 5714, and 5715 chips for now while we investigate the reported tx timeouts by Juergen Kreileder. Thanks to Juergen for reporting the problem. Update version to 3.60.

tg3 timeouts with 2.6.17-rc6
Hi, I'm seeing frequent network timeouts on my PowerMac G5 Quad with 2.6.17-rc6.

Juergen Kreileder I'm seeing frequent network timeouts on my PowerMac G5 Quad with 2.6.17-rc6. The timeouts are easily reproducible with moderate network traffic, e.g. by using bittorrent. Did this use to work with an older kernel or older tg3 driver? If yes, what version? Please also provide the full tg3 probing output during modprobe and ifconfig up.

Looking at the patch history since 2.6.16, the only patch that could have an impact is the one that enables TSO by default. Please try turning TSO off to see if it makes a difference: ethtool -K eth0 tso off Seems to work fine with TSO disabled.

Thanks for the information. We'll look into it. If possible, please send me (using private email) an ethereal trace of a sample of the packets sent by the tg3 chip right before the NETDEV_WATCHDOG timeout. In the meantime, I wonder if we should disable TSO by default on the 5780 chip for 2.6.17. - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
