You'll have to contact Digital Logic and have them check with the BIOS vendor to see if the fix was made in that version or not. I don't have that particular board, so I can't try out the fixes here.

Sure - you might as well - just to make sure its the same problem.

Chuck, Jordan, thanks for taking an interest in this problem. As suggested by Jordan I tried a new BIOS revision from http://www.digitallogic.ch/index.php?id=256=/MSEP800%20-%20SM800PCX%20%20-%20MPC20%20-%20MPC21=23 Unfortunately the kernel still fails to boot in the same way.

Its hitting a bug - specifically (from bootmem.c:125): BUG_ON(PFN_DOWN(addr) >= bdata->node_low_pfn); I hit this problem on a db800 last week. It went away with a newer version of the BIOS, which doesn't help Joerg any, since its a different board (though I think it is the same BIOS vendor). Other BIOSes work just fine with the same kernel image (including known troublemakers like LinuxBIOS). I believe that 2.6.22 was good, so some change must have come along in 2.6.23-pre to cause the pain. Or, it may have exposed old breakage in the BIOS that was later repaired. I'll do the math to figure out whats happening - and I'll check the release notes to see what changed in the BIOS between the failing and working version. If anybody familiar with arch/i386 can think of something new in the kernel that may have precipitated this, do let me know. :) Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
