Hello, My Sun Fire V100's don't seem to be able to boot a custom kernel >2.4.21:
SILO Version 1.4.4 boot: 2.4.25-lvs -p Allocated 8 Megs of memory at 0x40000000 for kernel Loaded kernel version 2.4.25 Illegal Instruction ok (the -p flag doesn't seem to matter) The weird thing is.. I have 2 Sun Netra X1's and 2 Sun Fire V100's which are about the same (apart from the CDROM drive). I have build one kernel image (on one of the Netra's) that works ok with the Netra's but the Fire's are crashing with the error above. /proc/cpuinfo @ netra's: cpu : TI UltraSparc IIe (Hummingbird) fpu : UltraSparc IIe integrated FPU promlib : Version 3 Revision 0 prom : 4.0.6 type : sun4u ncpus probed : 1 ncpus active : 1 Cpu0Bogo : 799.53 Cpu0ClkTck : 0000000017d78400 MMU Type : Spitfire /proc/cpuinfo @ fire v100's: cpu : TI UltraSparc IIe fpu : UltraSparc IIe integrated FPU promlib : Version 3 Revision 0 prom : 4.0.18 type : sun4u ncpus probed : 1 ncpus active : 1 Cpu0Bogo : 1094.45 Cpu0ClkTck : 0000000020a9d100 MMU Type : Spitfire The kernel image (I tried 2.4.25 and 2.4.26-pre4) was build using gcc version 3.3.3-2 (Debian). Silo is 1.4.4-1. Compiling a seperate kernel image on the Fire's doesn't seem to matter. Any clues how to debug this or what to try next? Thanks! Willem PS. My .config is at http://www.cs.utwente.nl/~grootw/config-2.4.25-lvs.txt
