Hm, your start address is 0x80020000, but the load address of the jmr3927 (in the www.linux-mips.org tree) is 0x80050000. So maybe the address is wrong, comparing with the old 2.4 kernel should tell.
I compared that against the working 2.4.12 kernel, which does indeed have 80020000 in arch/mips/Makefile. I changed load-$(CONFIG...TX3927) to use 80020000 instead of 80050000, but it still fails the same way. There was also something that I had changed in our 2.4.12 that I had forgotten, but my coworker reminded me that, in jmr3927.h, I changed JMR3927_ROMCE0 from 0x1fc000000 to 0x1f000000 to have the proper address to access some raw memory for internal purposes. I do not recall whether that address is specific to our hardware or a typo, but I do not think that it impacts the normal kernel anyway.
Our 2.4.12 kernel uses -mcpu=r3000 -mips1 to build the kernel. I tried switching the arch to r3000 from r3900 in 2.6.23.9, but that did not help. Perhaps -mips1 or an equivalent could help? I will try on Monday.
I am grasping at straws here. Thanks to Thiemo and Florian for trying to help. Have a good weekend.
