Public bug reported:
I bought a brand new pc (AMD Athlon X2 5000+, m/b Asus M2N-SLI, 4GB 800Mhz,
Asus DRW-2014L1T) and I installed Ubuntu AMD64 on it.
I soon had a problem during installation, cause it didn't recognize the
DVD-rom; after some researches I booted with the flag "all_generic_ide" and was
able to install Ubuntu.
But with that option activated the performance of the hard disk was sluggish:
[EMAIL PROTECTED]:~$ sudo hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 1366 MB in 2.00 seconds = 683.07 MB/sec
Timing buffered disk reads: 28 MB in 3.18 seconds = 8.80 MB/sec
[EMAIL PROTECTED]:~$
So I removed "all_generic_ide", disk performances now seem fine (or
should I expect better results?):

but whenever I insert a CD/DVD the system *reboots*; no error, no kernel panic,
it just reboots. If I put "all_generic_ide" then I can read cd/dvs's fine.
Below are the lines in /var/log/messages just before those spontaeous
reboots which happen when I insert a dvd:

I tried to change the SATA cable of the DVD-RW, but with the same

Ask me if you need more logs.
