After spending 3 days tweaking, I figured it out! Gcc 3.2 / 3.3 seems unable to build a kernel for my Sun Fire V100. It compiles without fatal errors, but upon booting the Sun crashes:
SILO Version 1.4.4 boot: 2.4.25 -p Allocated 8 Megs of memory at 0x40000000 for kernel Loaded kernel version 2.4.25 Illegal Instruction ok I tried kernels 2.4.25, 2.4.26-pre3 and 2.6.4 and gcc 3.2 and 3.3 (from Debian Testing) but to no avail. Also, the Debian package kernel-image-2.4.24-sparc64_35_sparc.deb gives the same error. Luckily, compiling with egcs64_19980921 works ok! (through editing arch/sparc64/Makefile) The Sun Fire V100 is actually a Netra X1 plus a CDrom drive and upgraded PROM (4.0.18 in stead of 4.0.6). The Netra X1 works fine though with a gcc3 compiled kernel. Strange huh? But it gets stranger... Some years ago I bougt two Sun Fire V100's. Only this week I found out that they give different bootup messages: Sun Fire V100 (UltraSPARC-IIe 548MHz), No Keyboard OpenBoot 4.0, 768 MB memory installed, Serial #51606773. Ethernet address 0:3:ba:13:74:f5, Host ID: 831374f5. opposite to: Sun Netra X1 (UltraSPARC-IIe 548MHz), No Keyboard OpenBoot 4.0, 768 MB memory installed, Serial #51800813. Ethernet address 0:3:ba:16:6a:ed, Host ID: 83166aed. They have the same PROM (4.0.16) though. But.. the V100 which names itself X1, actually boots fine with a gcc3 compiled kernel. The other V100, which seems to be a true V100 (but also PROM 4.0.16) will only boot an egcs64-compiled kernel. I hope this information is useful for someone :) Willem
