I'll have to try and get around to that soon - I'm currently busy with some various work and can't afford the time just yet :/. Also, I just realized that I copied lkml and scsi without providing any useful context. Kernel is 2.6.15-ck1 with the Marvell sk98lin patch and (barf) nvidia.ko. I noticed after having the OOM killer make its rounds a few times that the slab layer was eating in excess of 600MB. lspci: 00:00.0 Host bridge: Intel Corporation 915G/P/GV/GL/PL/910GL Processor to I/O Controller (rev 04) 00:01.0 PCI bridge: Intel Corporation 915G/P/GV/GL/PL/910GL PCI Express Root Port (rev 04) 00:1b.0 Class 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 2 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #3 (rev 03) 00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #4 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB2 EHCI Controller (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d3) 00:1f.0 ISA bridge: Intel Corporation 82801FB/FR (ICH6/ICH6R) LPC Interface Bridge (rev 03) 00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 03) 00:1f.2 Class 0106: Intel Corporation 82801FR/FRW (ICH6R/ICH6RW) SATA Controller (rev 03) 00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 03) 01:03.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link) 01:04.0 Mass storage controller: <pci_lookup_name: buffer too small> (rev 13) 01:09.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04) 01:09.1 Input device controller: Creative Labs SB Audigy MIDI/Game port (rev 04) 01:09.2 FireWire (IEEE 1394): Creative Labs SB Audigy FireWire Port (rev 04) 01:0a.0 SCSI storage controller: Adaptec AHA-7850 (rev 03) 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 Gigabit Ethernet Controller (rev 15) 04:00.0 VGA compatible controller: nVidia Corporation Unknown device 0092 (rev a1) config.gz attached. I'd also like to note that I've been getting this in my ring buffer when attempting to burn CD's on a PX-716A: (scsi0:A:4:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted (scsi0:A:4:0): Unexpected busfree while idle SEQADDR == 0x16a (scsi0:A:4:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted sr 0:0:4:0: SCSI error: return code = 0x70000 (scsi0:A:4:0): Unexpected busfree while idle SEQADDR == 0x16a (scsi0:A:4:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted (scsi0:A:4:0): Unexpected busfree while idle SEQADDR == 0x16a (scsi0:A:4:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted sr 0:0:4:0: SCSI error: return code = 0x70000 (scsi0:A:4:0): Unexpected busfree while idle SEQADDR == 0x16a (scsi0:A:4:0): No or incomplete CDB sent to device. scsi0: Issued Channel A Bus Reset. 1 SCBs aborted ...but I don't think this is directly related, because this has been happening since at least 2.6.13 iirc. Just being thorough. Apologies to lkml & scsi for the brief/confusing earlier message. > Cheers, > Con Thanks, Chase
