I experience this locking up on a desktop if I don't blacklist the ath5k module. It's new in Jaunty as well. Whilst it did first appear sometime around Jaunty moving from the beta to the release candidate, I also tried the Ubuntu kernel PPA release of 2.6.30rc4 ( http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc4/ ), but the same issues occur. I'm running no non-free or restricted kernel modules.
Finally, I encountered noise floor calibration issues in dmesg fairly frequently (I didn't save any of the logs to check) - it was akin to what's reported in https://bugzilla.redhat.com/show_bug.cgi?id=452491 however, in particular having that error message ("noise floor calibration timeout") I believe verbatim. It spammed dmesg so much that the boot messages in dmesg were gone within a few hours. However, I don't remember whether this also occurred in the working-(Ubuntu-Jaunty- beta)-kernel or whether its appearance correlates with the hard locks starting. relevant dpkg output: ii linux-image-2.6.28-11-generic 2.6.28-11.42 Linux kernel image for version 2.6.28 on x86 ii linux-image-2.6.30-020630rc4-generic 2.6.30-020630rc4 Linux kernel image for version 2.6.30 on x86 ii linux-image-generic 2.6.28.11.15 Generic Linux kernel image ii linux-restricted-modules-2.6.28-11-generic 2.6.28-11.15 Non-free Linux kernel modules for version 2. ii linux-restricted-modules-common 2.6.28-11.15 Non-free Linux 2.6.28 modules helper script ii linux-restricted-modules-generic 2.6.28.11.15 Restricted Linux modules for generic kernels Abridged lspci information: 05:00.0 Ethernet controller: Atheros Communications Inc.
