Thanks for the information. I'll see if I can root cause it. LMT is basic enough that it cannot cause a bug by itself. Issue to resolve is is which knob, being tweaked by LMT, is triggering a bug elsewhere in the kernel.
On my machine the cpufreq module of LMT is marked as "auto". With that, following is my lsmod result: 01:08:04 rrs@champaran:~/Community/Packaging/pkg-fcoe/fcoe-utils (master)$ lsmod | grep -i cpu acpi_cpufreq 12935 1 mperf 12453 1 acpi_cpufreq cpufreq_stats 12866 0 cpufreq_userspace 12576 0 cpufreq_conservative 13147 0 cpufreq_powersave 12454 0 xt_tcpudp 12570 25 x_tables 19028 16 ebtables,ipt_MASQUERADE,iptable_nat,xt_CHECKSUM,iptable_mangle,xt_hl,ip6t_rt,ipt_REJECT,xt_limit,xt_tcpudp,xt_addrtype,xt_state,ip6table_filter,ip6_tables,iptable_filter,ip_tables processor 27949 3 acpi_cpufreq Can you confirm the contents of /etc/laptop-mode/conf.d/cpufreq.conf ? And by the way, how persistent is the bug you are seeing? On my laptop, the issue is intermittent. On Wednesday, December 28, 2011, Jardi A.
