Re: PROBLEM: 2.6.20-1 not working on ibook g4 (BUG/Oops)
Hi, i'm happy to report that i've been able to boot my ibook without any error, using Ken Moffat's .config (thanks again Ken!) as a base. I'm putting the prominent part here for completeness. I still have no idea what caused these errors, but at least i'll try to find what was compiled with the failing config that is not compiled anymore with this one.

Unfortunately, i can't use a serial console, and netconsole refused to work (both built as a module and within the kernel). However, after some 20 shots to my laptop screen (God bless digital cameras) i had luck and could hand-copy something out of a shot; i _really_ hope it helps: Modules linked in: snd_aoa_codec_tas snd_aoa_fabric_layout snd_aoa snd_aoa_i2sbus snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_page_alloc appletouch snd soundcore snd_aoa_soundbus uninorth_agp agpgart eth1394 evdev ext3 jbd mbcache dm_mirror dm_snapshot dm_mod usbhid ff_memless ide_cd cdrom ide_disk sungem sungem_phy ohci1394 ieee1394 ehci_hcd ohci_hcd usbcore i2c_powermac NIP: C007BBA8 LR: C007BA00 CTR: 0029 REGS: cfc13990 TRAP: 0300 Not tainted (2.6.20.1-powerpc) MSR: 1032 CR: 22004042 XER: DAR: , DSISR: 4200 TASK = c1b83950[2309] 'alsactl' THREAD: cfc12000 GPR00: 00200200 CFC13A40 C1B83950 C1BF901C 0015 0028 C1C97D60 C1BF9000 GPR08: 00100100 0151A7A0 100D8C9C C1AFE19C GPR16: CFC13D18 0009 0001 0007 EFFB4800 C1A77D34 C1A77D90 GPR24: 0010 00011200 EFFEE6E0 C1C9D260 C1C96A00 NIP [C007BBA8] cache_alloc_refill+0x184/0x564 LR [C007BA00] kmem_cache_alloc+0x6c/0x90 Call Trace: [CFC13A40] [0020020] 0x20020 (unreliable) [CFC13A70] [C007BA00] kmem_cache_alloc+0x6c/0x90 [CFC13A90] [C005E86C] mempool_alloc_slab+0x1c/0x2c [CFC13AA0] [C005EAA0] mempool_alloc+0x44/0xf4 [CFC13AE0] [C00F08C4] get_request+0x184/0x294 [CFC13B10] [C00F12A4] get_request_wait+0x28/0x100 [CFC13B60] [C00F2254] __make_request+0x3b4/0x550 [CFC13BB0] [C00EFCA0] generic_make_request+0x208/0x224 [CFC13BF0] [C00F2810] submit_bio+0xe4/0xf8 [CFC13C30] [C00A3D9C] submit_bh+0x160/0x198 [CFC13C50] [C00A5178] ll_rw_block+0x104/0x134 [CFC13C70] [F22C95F8] ext3_find_entry+0x308/0x524 [ext3] [CFC13D10] [F22CB24C] ext3_lookup+0x34/0x134 [ext3] [CFC13D40] [C0087A44] do_lookup+0xc0/0x1a0 [CFC13D70] [C0089EB0] __link_path_walk+0x904/0xe70 [CFC13DC0] [C008A49C] link_path_walk+0x80/0x144 [CFC13E30] [C008A8AC] do_path_lookup+0x1f8/0x22c [CFC13E60] [C008B350] path_lookup_intent_open+0x58/0xa4 [CFC13E80] [C008B504] open_namei+0x6c/0x698 [CFC13EC0] [C007D794] do_filp_open+0x30/0x60 [CFC13F20] [C007D81C] do_sys_open+0x58/0xf8 [CFC13F40] [C00129F4] ret_from_syscall+0x0/0x40 --- Exception : c01 at 0x30012cf8 LR = 0x300056a4 Instruction dump: 801c0020 38890001 7f890040 409c000c 38a5 4200ffac 8127 3d600010 3c20 81470004 616b0100 6200 <912a> 91490004 9167 90070004 I have to add some more info: - sometimes i'm having another error with the same kernel, but in a different moment (earlier).

Re: PROBLEM: 2.6.20-1 not working on ibook g4 (BUG/Oops)
Hi, I have to correct myself: 2.6.19-7 just freezes randomly. At this point, the last surely working kernel i am aware of is 2.6.18, built from debian sources. Actually i'm trying (for the very first time) to git-bisect Linus' tree, to see if i can figure out something, but i feel my chances are extremely low..

Re: PROBLEM: 2.6.20-1 not working on ibook g4 (BUG/Oops)
Hi, I have to correct myself: 2.6.19-7 just freezes randomly. At this point, the last surely working kernel i am aware of is 2.6.18, built from debian sources. Actually i'm trying (for the very first time) to git-bisect Linus' tree, to see if i can figure out something, but i feel my chances are extremely low..

Can you use a serial console or netconsole to send to kernel messages to another computer? Unfortunately, i can't use a serial console, and netconsole refused to work (both built as a module and within the kernel).
