Troubleshooting
- Problem: CDRW is not recognized
- Error message in /var/log/messages: ata2.00: failed to set xfermode (err_mask=0x4)
- Solution from Feisty doesn't recognize cd burner:
- 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
- Solutions:
- A generic solution from ATI: X Fails to Load on Systems with Linux Kernel Version 2.6.x
- An exact solution that worked: AGP not detected on Intel 8285P and E7205 chipsets using kernels higher than 2.6.17
- # 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
