Hallo all of you, I need some help here interpreting. I do not read "kernel" very well! Last week I set up kernel 2.6.30-5 to be a real time kernel with aid of RTAI 3.8 package. so since last week I had 2 kernel crashes which both seem to involve nilfs in more or less the same way. In the first case there was no real time stuff started or running and in the second case it was just unloaded. Regards, Jan de Kruyf. here are the log traces Apr 10 00:09:16 debianLenny ntpd[2887]: synchronized to 196.25.1.9, stratum 2 Apr 10 00:11:54 debianLenny kernel: [ 3889.584373] ------------[ cut here ]------------ Apr 10 00:11:54 debianLenny kernel: [ 3889.584384] WARNING: at kernel/sched.c:4917 sub_preempt_count+0x8a/0x90() Apr 10 00:11:54 debianLenny kernel: [ 3889.584386] Hardware name: OEM Apr 10 00:11:54 debianLenny kernel: [ 3889.584387] Modules linked in: i915 drm i2c_algo_bit video output nfsd lockd nfs_acl auth_rpcgss sunrpc autofs4 dm_crypt irtty_sir sir_dev irda crc_ccitt snd_hda_codec_realtek processor i2c_i801 snd_hda_intel snd_hda_codec snd_pcm snd_seq snd_timer snd_seq_device snd intel_agp soundcore agpgart snd_page_alloc usbhid r8169 mii floppy thermal [last unloaded: scsi_wait_scan] Apr 10 00:11:54 debianLenny kernel: [ 3889.584423] Pid: 1661, comm: segctord Not tainted 2.6.30.5-rtai #1 Apr 10 00:11:54 debianLenny kernel: [ 3889.584425] Call Trace: Apr 10 00:11:54 debianLenny kernel: [ 3889.584429] [<c0524dba>] ?
