I tend to use l (show-backtrace-all-active-cpus) as this doesn't dump too much junk to dmesg. Above the backtraces you'll get a modules linked in line which shows taint status for individual modules: SysRq : Show backtrace of all active CPUs sending NMI to all CPUs: NMI backtrace for cpu 0 CPU 0 Modules linked in: dm_snapshot nfsd exportfs ebtable_nat ebtables ipt_MASQUERADE iptable_nat nf_nat xt_CHECKSUM iptable_mangle bridge stp llc vhost_net macvtap macvlan tun kvm_intel kvm cachefiles nfs lockd fscache(T) nfs_acl auth_rpcgss autofs4 sunrpc ipt_REJECT ^^^^^^^^^^ nf_conntrack_ipv4 nf_defrag_ipv4 iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 ext3 jbd power_meter microcode dcdbas serio_raw iTCO_wdt iTCO_vendor_support igb dca i7core_edac edac_core sg bnx2 ext4 mbcache jbd2 sd_mod crc_t10dif mpt2sas scsi_transport_sas raid_class dm_mirror dm_region_hash dm_log dm_mod [last unloaded: speedstep_lib] Pid: 0, comm: swapper Tainted: G ---------------- T 2.6.32-216.el6.x86_64 #1 Dell Inc.
