[coreboot] m57sli, seabios and gpxe - kernel booting issues (BUG: INT 14 etc)
Hi Kevin et al, I'm trying to do a GPXE boot from seabios with coreboot on m57sli, and I'm not getting very far. I'm using git/svn head for GPXE, seabios and coreboot. I've tried various kernels - 2.6.22, 2.6.24, 2.6.27, 2.6.28 and 2.6.30 (all ubuntu prebuilt kernels). With 2.6.30, I get absolutely nothing, the kernel just hangs without output. That's with the multi-segment patched mkelfImage or with the ordinary older mkelfImage. With 2.6.28-13-generic I get (manually copied, so there might be transcription errors in this...): BUG: Int 14: CR2 b0f0 EDI ESI EBP c072bf3c ESP c072bf1c EBX 0046 EDX 000e ECX EAX b0f0 err EIP c0119891 CS 0060 flg 00010046 Stack: c011a26e 0046 0046 c072bf48 c0118a66 00f3390c c072bf60 c04fcb2f c05f62e0 c07dba60 00f3390c c072bfb8 c073b44c c05eb8b0 0080 00f3390c c05f2c18 0010 008760ab With 2.6.27-14-generic I get PANIC: early exception 0e rip 10:8022d621 error 0 cr2 5fc0f0 I found some references online that that panic might be caused by a kernel bug, fixed in 2.6.27.2. However, the same kernel boots fine if booted directly from seabios (from disk). In fact, *all* the kernels I tried boot fine from disk. So is GPXE doing something funky here, or is there something else going on? Thanks, Ward. -- Ward Vandewege w...@fsf.org Free Software Foundation - Senior Systems Administrator -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot

Can you send GPXE some other ELF files? Anything that works as a payload with coreboot should do for a test. tint, invaders, coreinfo whatever. //Peter -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
