Problem booting malta with 2.4.33-rc1

[-- Attachment #1.1: Type: text/plain, Size: 580 bytes --]

Hi,
When trying to bring up Malta (4KC) board with 2.4.33-rc1 from linux-mips,
the kernel crashes. Boot log is enclosed along with this mail. I am using
the tool chain based on gcc 3.3.6, uClibc-0.9.27, binutils 2.14.90.0.8.
When the same tool chain is used for 2.4.31 kernel, the board comes up
without any issues.

Observed the same issue with tool chain based on gcc 3.4.4, uClibc-0.9.28,
binutils 2.15.94. Same result is observed even with  Malta 24KEC and
2.4.33-rc1 kernel.

Does any one observe the same behaviour ? Am I missing something obvious
here ?

thanks,
--kishore

I have seen the same problem with gcc 3.4.4 mipssde-6.03.01-20051114 and
 binutils 2.15.94 mipssde-6.03.01-20051114 with 2.6.6 kernel.
gcc 3.3.2 and binutils 2.14.90.0.8 20040114 has no problem with same kernel.

Linux 2.4 has known issues with gcc 3.4 and higher, gcc 3.3 is the last
recommended version. The Malta configuration was fixed at some point to
work with 3.4, other configurations weren't.

The usual recommendation is an upgrade to a reasonably recent Linux 2.6. :-)

Last I checked IP22 defconfig for example didn't even build with gcc 3.4.

A kernel update.  2.4.33-rc2 fix a number of Malta issues or better 2.6.

Note that fixing any issues in 2.4 has next to null priority these days.
Read somewhere below watching paint dry.

 It's a latest 2.4 kernel from the linux-mips GIT w/o any modification.
Note, it's a generic mips-linux kernel, not a special mips-malta.

 My toolchain is gcc 3.3.6 from the Buildroot-20060523  snapshot.


 There were some modification made between 2.4.32 and 2.4.33-pre2 :

1) The MIPS32 FPU save-restore support. There was no MIPS32
support in the 2.4 before the 2.4.33-pre2.
2) PCI and PC-style COM-port issue resolved
