XFS Kernel issues and CD Burner

[compucoder]

Hi, I just did a new clean install of linux. I setup the system basically the same way each time I do an install. From stage1 - same USE vars, same CFlags, etc.

Every other time I was able to get my cd burner to work. This time I cant get it detected as a burner at all.

The XFS sources this time are 2.4.20 instead of 2.4.19 - not sure if that broke scsi emulation stuff. The one thing that I find very strange and unsafe in my opinion is that the kernel is compiling a majority of files using -O3 and -fomit-frame-pointer -i686. I am wondering if this high level of optimizations is safe for building a kernel with?? I think i firced my last kernel to -O3 before for a test and it broke things on me.

Anyone else have an opinion on this? O3 and i686 too risky for kernel compiling?

Here is my cdrecord -scanbus info to be thorough it looks nasty so maybe it will show that I am an idiot and forgot something important
ie, hdc=ide-scsi is in the boot - scsi cd-rom, scsi-generic and scsi emulation are compiled into the kernel

Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J?rg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

thanx

like to update for those following this thread. As i suspected it was due to the kernel being built using -O3. I recompiled the kernel using -Os and now everything works as it should. The system is even faster than it was before. Seems that O3 is unpredictable to be using for things. Especially kernel compiling.

Still unsure why the makefile is choosing -O3 as the default. Risky in my opinion :/
