I haven't reported kernel bug until now. I'll try to send as much information as I can. I hope it is sufficient. 1. I see repeating (flood) messages "Oct 27 13:14:59 mclive5 kernel: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1" in my syslog - once per second. 2. Frequency is probably one message per second because I see this on every 61 seconds: "last message repeated 61 times". I'm not sure if the problem is in the driver or in OS because I use Centos 5.5 with newer kernel, but I don't have the same problem with other network adapters. R6040 is build into kernet, not as a module. 3. keywords: modules, networking, kernel, problem, linkup, syslog, r6040, MicroClient JrMX 4. kernel version - # cat /proc/version Linux version 2.6.35.7-ns.i586 (root@localhost.localdomain) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #15 Thu Oct 21 18:26:55 CEST 2010 SMP is disabled 5. 6. The problem is always presend. doesn't have to trigger it. only bring interface up: ifconfig eth0 up 7.1 Operating system is Centos 5.5 without updates. it's run as livecd (my own modification). initrd is completely rewritten - it uses bash for init script. init script just mounts the filesystem and ends with: exec chroot . /bin/bash <<- EOF >/dev/console echo "running init" exec /sbin/init $level EOF root filesystem is AUFS that consists of: one squashfs image one tmpfs ram disk with size=200M 7.2. processor info: Processor is Xcore86 MX at 1 GHz and it is i586 compatible /proc/cpu reports Vortex86 SoC flags : fpu tsc cx8 7.3 module information: # cat /proc/modules ipv6 216009 16 - Live 0xe08ba000 hidp 9827 2 - Live 0xe086b000 l2cap 33993 5 hidp, Live 0xe0875000 crc16 995 1 l2cap, Live 0xe085d000 bluetooth 46244 2 hidp,l2cap, Live 0xe0842000 rfkill 7982 1 bluetooth, Live 0xe0824000 tun 12103 0 - Live 0xe0979000 dm_mirror 11560 0 - Live 0xe0967000 dm_region_hash 5376 1 dm_mirror, Live 0xe0957000 dm_log 7531 2 dm_mirror,dm_region_hash, Live 0xe094a000 dm_multipath 14155 0 - Live 0xe092e000 scsi_dh 3972 1 dm_multipath, Live 0xe091f000 dm_mod 52849 3 dm_mirror,dm_log,dm_multipath, Live 0xe0903000 option 12594 0 - Live 0xe08b4000 usb_wwan 6820 1 option, Live 0xe0899000 serio_raw 3328 0 - Live 0xe088c000 rtc_cmos 7326 0 - Live 0xe0880000 rtc_core 10393 1 rtc_cmos, Live 0xe0870000 pcspkr 1279 0 - Live 0xe0857000 rtc_lib 1477 1 rtc_core, Live 0xe0861000 7.4 Loaded driver and hardware information # cat /proc/ioports 0000-001f : dma1 0020-0021 : pic1 0040-0043 : timer0 0050-0053 : timer1 0060-0060 : keyboard 0064-0064 : keyboard 0070-0071 : rtc_cmos 0070-0071 : rtc0 0080-008f : dma page reg 00a0-00a1 : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : 0000:00:0c.0 0170-0177 : pata_rdc 01f0-01f7 : 0000:00:0c.0 01f0-01f7 : pata_rdc 02e8-02ef : serial 0376-0376 : 0000:00:0c.0 0376-0376 : pata_rdc 03c0-03df : vga+ 03e8-03ef : serial 03f6-03f6 : 0000:00:0c.0 03f6-03f6 : pata_rdc 03f8-03ff : serial 0cf8-0cff : PCI conf1 de00-deff : 0000:00:08.0 de00-deff : r6040 df80-dfff : 0000:00:0d.0 ef00-ef0f : 0000:00:0c.0 ef00-ef0f : pata_rdc # cat /proc/iomem 00000000-00000fff : reserved 00001000-0009fbff : System RAM 0009fc00-0009ffff : reserved 000a0000-000bffff : Video RAM area 000c0000-000c7fff : Video ROM 000e4000-000fffff : reserved 000f0000-000fffff : System ROM 00100000-1fffffff : System RAM 00400000-007c990c : Kernel code 007c990d-0095d2d7 : Kernel data 009c1000-00a40e37 : Kernel bss f8000000-fbffffff : 0000:00:0d.0 febc0000-febcffff : 0000:00:08.0 febd9000-febd9fff : 0000:00:0a.0 febd9000-febd9fff : ohci_hcd febda000-febdafff : 0000:00:0b.0 febda000-febdafff : ohci_hcd febdb400-febdb4ff : 0000:00:08.0 febdb400-febdb4ff : r6040 febdb800-febdb8ff : 0000:00:0a.1 febdb800-febdb8ff : ehci_hcd febdbc00-febdbcff : 0000:00:0b.1 febdbc00-febdbcff : ehci_hcd febdc000-febdffff : 0000:00:0e.0 febe0000-febfffff : 0000:00:0d.0 ff000000-ffffffff : reserved 7.5 PCI info: # lspci -vvv 00:00.0 Host bridge: RDC Semiconductor, Inc.
