[Bug bootstrap/34189] New: Kernel hangs while booting when compiled with gcc-4.3 snapshot.

[Ashay dot Jaiswal at kpitcummins dot com]

Hello all,      

I have successfully built SH4-Linux toolchain based on          
(binutils-2.17.50, gcc-4.3-20071012, glibc-2.6) for Renesas SH target   

I am facing problem while booting the Linux kernel on SH target.        
Targets Used for Testing: SH7751R2D+ and SH7780 Highlander RP   
I have successfully compiled Linux kernel using toolchain but           
kernel hangs after following message:           

Disk drive detected: TOSHIBA THNCF128MMG 3.10 STCB21M85008B24183C8      
Set Transfer Mode result: 51    
Initialize Device Parameters result: 50         
IDLE result: 50         
LILO boot: first-image          
Loading linux........................done.      

It is not even printing the banner of the kernel.               

The same kernel when compiled with gcc-4.2.1 based toolchain, it boots          
successfully on the target hardware             


Any help on this will be highly appreciated.            

Regards,

We need a testcase to do anything about this.

I have tested on released Linux kernel version 2.6.22.1 and kernel version      
2.6.23.1 both hangs while booting, but boots successfully when cross compiled   
with gcc-4.2.1 based toolchain.

Re. comment #3: noticing a failure is not a test case.  A test case is a piece
of example code that people can use to hunt this bug.  Just mentioning "my
kernel does not boot" is not a test case.

Please read http://gcc.gnu.org/bugs.html#report
