=20 -----Original Message----- From: Rupert Mazzucco [mailto:maz...@il...]=20 Sent: Monday, October 27, 2003 6:15 AM To: Grover, Andrew Cc: mi...@re... Subject: PROBLEM: kernel BUG in sched.c:564 I can't get most of the info suggested in REPORTING-BUGS because the buggy kernel crashes nearly immediately. Anyway, here's what happens: - System crashes with message "kernel BUG in sched.c:564", complaining about an "invalid operand: 00000" (all zeros) and register information etc. I don't see an "oops", though, but nothing goes anymore. This happens in the simplest case directly after booting into text mode if I wait some minutes (without login). I can login and issue a few commands if I'm quick enough, but didn't manage to do more than a "cd" and a "ls". - System in question is 2.4.22 + acpi-20031002 patch. Build system is gcc 3.3 + assorted tools. Hardware is a Acer TM 521 notebook w/ PIII. (I could build and run a 2.4.21 + ACPI kernel without problems.) - The offending function in sched.c looks like there was something wrong with the interrupts. I notice that the buggy kernel writes a message "ACPI: IRQ 9 was Edge Triggered, setting to Level Triggerd" [sic!], which didn't appear in earlier kernels. This is why I think it may be really an ACPI problem. - output of scripts/ver_linux: Linux darkstar 2.4.21 #1 Mon Jun 30 17:49:45 CEST 2003 i686 unknown [this is *not* the kernel that crashes, see above] =20 Gnu C 3.3 Gnu make 3.80 util-linux 2.11z mount 2.11z modutils 2.4.22 e2fsprogs 1.32 pcmcia-cs 3.2.4 PPP 2.4.1 Linux C Library 2.3.2 Dynamic linker (ldd) 2.3.2 Procps 3.1.6 Net-tools 1.60 Kbd 1.08 Sh-utils 2.0 Modules Loaded mach64 af_packet e100 [crashes without those modules, see above] - boot messages from the buggy kernel from syslog: Oct 27 13:49:49 darkstar kernel: Linux version 2.4.22+acpi-20031002 (root@darkst ar) (gcc version 3.3) #1 Mon Oct 27 12:43:00 CET 2003 Oct 27 13:49:49 darkstar kernel: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 0000000000100000 - 0000000007ff0000 (usable) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 0000000007ff0000 - 0000000007ff8000 (ACPI data) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 0000000007ff8000 - 0000000008000000 (ACPI NVS) Oct 27 13:49:49 darkstar kernel: BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) Oct 27 13:49:49 darkstar kernel: On node 0 totalpages: 32752 Oct 27 13:49:49 darkstar kernel: zone(0): 4096 pages.
