My guess is the sata_nv driver, as it happens during heavy local file read. The machines all have 2-4 SATA WD Raptors connected to the mobo. > I don't run these kernels though - only mainline. I wouldn't expect you to be running a Fedora kernel. :-p I usually roll my own, but I've been really backed up with other tasks. As I said, I'll build some mainline kernels. I want to apply some of Ingo's debugging patches and give John Stultz's new timekeeping code a try anyway. rugolsky@ti94: cat /proc/interrupts CPU0 CPU1 0: 28474 577049 IO-APIC-edge timer 1: 8 0 IO-APIC-edge i8042 7: 2 0 IO-APIC-edge parport0 8: 40 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-level acpi 14: 36 21506 IO-APIC-edge ide0 50: 3 0 IO-APIC-level ohci1394 201: 0 0 IO-APIC-level libata, ehci_hcd:usb1 209: 1876 15495 IO-APIC-level libata, ohci_hcd:usb2 217: 2483567 0 IO-APIC-level eth0 233: 0 0 IO-APIC-level NVidia CK804 NMI: 87 41 LOC: 605510 605486 ERR: 0 MIS: 0 Lots-o-modules; I'll have to whittle these down. rugolsky@ti94: lsmod Module Size Used by parport_pc 65581 1 lp 49025 0 parport 77261 2 parport_pc,lp nfs 275745 4 lockd 107601 2 nfs nfs_acl 37185 1 nfs sunrpc 210041 4 nfs,lockd,nfs_acl 8021q 57041 0 video 52553 0 button 41185 0 battery 44233 0 ac 38985 0 ohci1394 71457 0 ieee1394 407641 1 ohci1394 ohci_hcd 57565 0 ehci_hcd 70477 0 i2c_nforce2 41409 0 i2c_core 59457 1 i2c_nforce2 snd_intel8x0 70889 0 snd_ac97_codec 146045 1 snd_intel8x0 snd_ac97_bus 36033 1 snd_ac97_codec snd_seq_dummy 37445 0 snd_seq_oss 71973 0 snd_seq_midi_event 42177 1 snd_seq_oss snd_seq 99225 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 43857 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 93297 0 snd_mixer_oss 52673 1 snd_pcm_oss snd_pcm 139593 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 62025 2 snd_seq,snd_pcm snd 103073 9 snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq, snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 45025 1 snd snd_page_alloc 46289 2 snd_intel8x0,snd_pcm forcedeth 60869 0 floppy 107993 0 ext3 179665 5 jbd 100073 1 ext3 raid1 56385 4 dm_mod 98697 4 sata_nv 44101 8 libata 98265 1 sata_nv sd_mod 53697 10 scsi_mod 195321 2 libata,sd_mod Thanks. -Bill - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
