ITRI SSTC & DRBL

  • 問題一:Ubuntu 10.04, 10.10, 11.04 都沒有 partimage 的 amd64 版本
    套件 partimage
        * dapper (admin): backup partitions into a compressed image file [universe]
          0.6.4-14: amd64 i386 powerpc
        * hardy (admin): backup partitions into a compressed image file [universe]
          0.6.7-1: i386
          0.6.4-17: amd64
        * lucid (admin): backup partitions into a compressed image file [universe]
          0.6.8-1: i386
        * maverick (admin): backup partitions into a compressed image file [universe]
          0.6.8-1: i386
        * natty (admin): backup partitions into a compressed image file [universe]
          0.6.8-1: i386
        * oneiric (admin): backup partitions into a compressed image file [universe]
          0.6.8-2build1: amd64 i386
    
  • 問題二: 網卡不被支援 - Debian GNU/Linux 6.0.2 (squeeze) 不行,Ubuntu 要 10.10 以後版本的預設核心才行。
    00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
    00:19.0 0200: 8086:1502 (rev 04)
    
    • 2.6.32-5-amd64 的 e1000e 不支援這個 pciid,所以改裝 3.0.0-1-amd64
      jazz@eagle:/lib/modules/2.6.32-5-amd64$ cat modules.alias | grep 1502
      alias usb:v16CAp1502d*dc*dsc*dp*ic*isc*ip* aircable
      alias pci:v00001131d00007133sv00005169sd00001502bc*sc*i* saa7134
      jazz@eagle:/lib/modules/2.6.32-5-amd64$ cd ..
      jazz@eagle:/lib/modules$ cd 3.0.0-1-amd64/
      jazz@eagle:/lib/modules/3.0.0-1-amd64$ cat modules.alias | grep 1502
      alias pci:v00008086d00001502sv*sd*bc*sc*i* e1000e
      alias usb:v16CAp1502d*dc*dsc*dp*ic*isc*ip* aircable
      alias pci:v00001131d00007133sv00005169sd00001502bc*sc*i* saa7134
      
  • 問題三:改裝 3.0.0-1-amd64 會有另外的問題,就是 initrd-pxe.3.0.0-1-amd64.img 無法正常載入 e1000e 的模組,會出現
    "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    "The driver of network card is NOT found!"
    "Is this kernel $kernel_ver too old so it does not support this network card ?"
    "Without network card driver, we can NOT go on!"
    "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
    "Now enter shell to debug..."
    
  • 但是在 shell 中不做任何動作,直接下 exit 之後,又可以正常網路開機。因此懷疑 3.0.0-1-amd64 的開機速度較快,或 modprobe 程序有誤。
  • <解法> 目前暫時修改 /usr/lib/mkpxeinitrd-net/initrd-skel/bin/insert-modules 加入 sleep 1 的描述,則可以順利開機。

  • 問題四:出現 drm 錯誤訊息
    [drm:pch_irq_handler] *ERROR* PCH poison interrupt
    [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid
    
  • <備註> 應該要關閉 IPv6 支援 - [參考] IPv6 addrconf: prefix with wrong length 修改 /etc/sysctl.conf 加入
    net.ipv6.conf.all.accept_ra = 0
    net.ipv6.conf.all.autoconf = 0
