I am wondering if there is any 2.6.26 mipsel kernel suitable for
running  on an QEMU emulated machine?
    
        

Yes, the Malta kernels can be used in QEMU.

Aurelien: can you update your QEMU mips page
http://www.aurel32.net/info/debian_mips_qemu.php to lenny/2.6.26?
  
      

FWIW, using the 2.6.18 kernels specified in the current page, I am
getting Error -3 while decompressing the initrd, as well as random
instruction bus errors, memory corruption, etc (it differs from boot to
boot, sometimes makes it to the installer, sometimes not) - one such
attempt (all proceeds normally up to this point):

...

I am using qemu on ubuntu/amd64 (intrepid and hardy) but I don't think
the ubuntu qemu packages are so bad that it would explain this?

    

I am not able to reproduce those problems, even with the ubuntu/amd64
package (installed on a Debian Lenny). Are you using the exact command
line from this page to launch qemu?


  

Sure enough, I wasn't using the exact command on your page. The offending parameter (at least in terms of the Error -3's, which happen every time, as opposed to the bus errors, etc. which were intermittent) seems to be "-m 512" to increase available memory. Looks like the thresshold for the problem is between "-m 507" and "-m 508". Is this a known problem?

Thanks!
