But it can perfectly run Debian, so it should run kexec as well, shouldn't it? ;) > However, could you kexec a kernel from a kernel that has > CONFIG_MIPS_UNCACHED set (under "Kernel hacking", "run uncached")? > this will slow down the kernel that does the kexec, but if this works, > then it is most probably a cache problem. > > Could you also indicate the last lines of kernel messages just before > the "Bye." ? I'll try that later today and will post the results. > Are you trying to kexec a big kernel image ? Hmm, is it big? It's the same kernel I booted: # ls -l vmlinux -rwxr-xr-x 1 root root 3868065 May 26 23:30 vmlinux > how much RAM do you have > on the board ? It has 32 MB RAM; some ~11 MB is used before I load another kernel. > are there some hardware that could have a hard time to > be re-probed by the kexeced linux kernel ? The kexeced kernel is the same one I booted, so no. -- Tomasz Chmielewski http://wpkg.org _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
