Upon booting the system, after the kernel identifies each of my 4 IDE devices, it crashes immediately telling me about a BUG in sched.c. (Please see the included URL for a bit more info on this.) The bug also happens for others on various systems, though none of us can seem to discern why. Also, I tried compiling a kernel from scratch with default options and a kernel with all SCSI emulation and support removed, which did nothing against this problem. Reproducible: Always Steps to Reproduce: 1. Compile a 2.4.20-r1 kernel 2. Boot it under certain hardware (A guess) Actual Results: The kernel panics after booting into the new kernel. Expected Results: Booted up normally. My system is not overclocked. My current system is a Tyan TigerMP, standard Athlon MPs (1800), 512MB ECC DDR. (checked with memtest86, no errors.) The hard drive is a Western Digital 80 gigabyte JB series. Kernel 2.4.19r10 works with no errors at all, and changing it's configuration around doesn't hurt anything. The problem was introduced somewhere in .20. The URL http://forums.gentoo.org/viewtopic.php?t=38357 includes some extra info, including my .config.
Hmm... can you test with XFS-sources and or lolo-sources (as your time and resources allow?) that would be a great help in diagnosing this.
Sure, I'm testing the other sources now, expect an update shortly.
I just tested the lolo sources, and they include the exact same problem as the gentoo-sources. Same error with lun0, during the partition check: Partition check: /dev/ide/host0/bus0/target0/lun0: p1 p2 p3 /dev/ide/host0/bus0/target1/lun0:kernel BUG at sched.c:1103! Testing XFS next...
Just testing the XFS sources as well, they work as expected, no problems at all. Just the lolo and gentoo sources appear to be failing. Hope this helps!
I'd assume that your IDE controller is probably not supported by the 'old IDE core' the xfs-sources have the 'new IDE core' in them. Until you see a note in the gentoo-sources changelog to the effect of includingt he new IDE core, OR they are updated to a 2.4.21 version, stick tot he XFS sources on this hardware. Thanks!
If I could get a quick clarification, I'm wondering why the .19-r10 gentoo sources are able to work? Aren't they using the "old" IDE core as well? (Pardon my cluelessness, just was thinking aloud and that came up.) I'm aware there are changes in the code...just was wondering if you had any specific ideas about what changed. Thanks right back at you for the quick response! I'm more than happy to build stuff anyway...it's not a problem. :)
Alot of changes to ide were made from 2.4.19 > 2.4.20 as it goes.. broke some and fixed some. 2.4.21 should be back in shape
I'm experiencing the same problem. I tried XFS sources and they failed too.
