i686 4G/4G Kernel Problem Tracking
Last modified: 2007-11-30 17:10:40 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040404 Firefox/0.8 Description of problem: CONFIG_X86_4G=y 4G/4G memory split was enabled in all i686 FC2 development kernels after version .118. This has caused several problems with various kernel components that need to be individually isolated, confirmed and fixed. This is the master tracking bug for both suspected and confirmed 4G/4G problems. Please nominate bug numbers as comments within this report, and add it to the Bug dependency list after they are confirmed 4G/4G problems. http://people.redhat.com/wtogami/temp/4G/ For your convenience I will try to maintain the latest FC2 devel i686 kernels rebuilt here with 4G/4G disabled in order to aid end-user testing. Please test both the official kernel and this rebuilt test kernel and report any differences in behavior.
there is no such thing as "the" 4g/4g bug nor is 4g/4g broken so this tracking bug makes no sense really.
I have a problem that was previously diagnosed as this one, if it is not this problem, please let me know what extra info you need to classify the bug. kernel-2.6.5-1.326 I have cold booted my notebook with no PCMCIA devices (ie. without the card which invokes the previously noted buggy hermes driver). I have booted without rhgb and with initdefault 3 so as to never run X. The first suspend is successful and reports some messages, namely: divert: not allocating divert_blk for non-ethernet device sit0 arch/i386/kernel/time.c:178: spin_lock(arch/i386/kernel/time.c:0232be08) already locked by arch/i386/kernel/time.c/298 arch/i386/kernel/time.c:305: spin_unlock(arch/i386/kernel/time.c:0232be08) not locked blk: queue 19d93c00, I/O limit 4095Mb (mask 0xffffffff) I can resume OK 50% of the time it seems. On the second suspend / resume the machine starts the fan and hangs. Starting the fan is what happens on a cold boot. lspci output: 00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 00:07.0 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 03) 00:0b.0 Ethernet controller: Accton Technology Corporation EN-1216 Ethernet Adapter (rev 11) 00:0c.0 CardBus bridge: Texas Instruments PCI4451 PC card Cardbus Controller 00:0c.1 CardBus bridge: Texas Instruments PCI4451 PC card Cardbus Controller 00:0c.2 FireWire (IEEE 1394): Texas Instruments PCI4451 IEEE-1394 Controller 00:0e.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12) 00:0e.1 Communication controller: ESS Technology ESS Modem (rev 12) 01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64) Other kernels in the 2.4 series work well.
