FWIW, I was running 2.6.23-rc5 on my laptop (along with iwlwifi-0.1.14 for wireless) and I saw the same symptom: panic (blinking capslock) while in X. I saw one panic out of maybe 12 hours of uptime over a few reboots. The same system is quite stable with the stock Ubuntu 2.6.22 kernel.
My laptop is a Thinkpad X60s (core duo) so quite a different system. I'm traveling at the moment so I probably won't be able to gather much debugging info until next week. - R. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
