Troubleshooting

  • Problem: CDRW is not recognized
Error message in /var/log/messages: ata2.00: failed to set xfermode (err_mask=0x4)
Add the word 'irqpoll' (without quotes) to the kernel line in /boot/grub/menu.lst
  • Problem: Xorg starts up but no DRI with ATI Radeon 9600 Pro, Intel i875P chipset, Ubuntu Feisty
Error in /var/log/messages: unable to acquire AGP, error "xf86_ENODEV", cannot init AGP
# rmmod i82875p_edac
# rmmod edac_mc
# rmmod fglrx
# rmmod intel-agp (or another appropriate module from /lib/modules/`uname -r`/kernel/drivers/char/agp)
# rmmod agpgart
# modprobe agpgart
# modprobe intel-agp (or another appropriate module from /lib/modules/`uname -r`/kernel/drivers/char/agp)
# modprobe fglrx
blacklist the modules e7xxx_edac and edac_mc; e.g., add the following two lines at the beginning of /etc/modprobe.d/blacklist:
blacklist i82875p_edac
blacklist edac_mc
