Yes it is a custom built kernel. No I do not have kernel debugging on. It is a problem with openafs. I tried compiling openafs in the kernel directory for 2.6.28 that I compiled openafs in successfully earlier with apparently an older openafs and the newer openafs in squeeze fails the same as it did in the 2.6.30 kernel compile. Here is a grep of all DEBUG settings in .config CONFIG_X86_DEBUGCTLMSR=y CONFIG_ACPI_DEBUG=y CONFIG_IRDA_DEBUG=y CONFIG_MAC80211_DEBUG_MENU=y CONFIG_MAC80211_TKIP_DEBUG=y CONFIG_IEEE80211_DEBUG=y CONFIG_PNP_DEBUG_MESSAGES=y CONFIG_THINKPAD_ACPI_DEBUG=y CONFIG_ATH5K_DEBUG=y CONFIG_DEBUG_BUGVERBOSE=y CONFIG_DEBUG_MEMORY_INIT=y As I said, a previous openafs did compile with these DEBUG settings. I tried to turn off all of these but I couldn't. Apparently, some dependency is preventing turning them off. I see the same bug being reported in Gentoo.
