I can't reproduce the bug myself, but I have users who do the tests, and those users report that debian and ubuntu works great for them. this bug also happened with linux 2.6.12 ====================================================================== ---------------------------------------------------------------------- bugmenot - 04-03-06 01:31 ---------------------------------------------------------------------- I get the same crash with linux 2.6.16 and gentoo (gentoo-sources-2.6.16-r1) on an iBook G3 The oops I get: Unable to handle kernel paging request for data at address 0x00000002 Faulting instruction address: 0xc0163bac Oops: Kernel access of bad area, sig: 11 [#1] Modules linked in: snd_powermac snd_pcm snd_page_alloc airport orinoco hermes af_packet sungem sungem_phy usbhid snd_seq snd_timer snd_seq_device snd soundcore evdev ohci_hcd usbcore unix NIP: C0163BAC LR: EA106248 CTR: C0163B8C REGS: dd601cc0 TRAP: 0300 Not tainted (2.6.16-gentoo-r1) MSR: 00009032 CR: 22028484 XER: 20000000 DAR: 00000002, DSISR: 40000000 TASK = c18a6bd0[6967] 'modprobe' THREAD: dd600000 GPR00: EA106248 DD601D70 C18A6BD0 00000000 00000001 00000060 00000000 00000001 GPR08: 00000002 00000000 00000070 C0163B8C 22028482 1001E7A0 00000000 10001144 GPR16: 00002000 00000000 00000003 1002AF18 10000000 10000000 10000000 100170F8 GPR24: 00000000 100170B4 100170A8 DE800800 E6D6C7A0 0000000A EA10E14C 00000000 NIP [C0163BAC] i2c_smbus_write_byte_data+0x20/0x44 LR [EA106248] send_init_client+0x40/0xd8 [snd_powermac] Call Trace: [DD601D70] [C00465B0] setup_irq+0x100/0x144 (unreliable) [DD601DB0] [EA106248] send_init_client+0x40/0xd8 [snd_powermac] [DD601DD0] [E906DF00] snd_pmac_tumbler_post_init+0x28/0x78 [snd_powermac] [DD601DE0] [E906C31C] snd_pmac_probe+0x31c/0x334 [snd_powermac] [DD601E10] [C0143214] platform_drv_probe+0x20/0x30 [DD601E20] [C0140E0C] driver_probe_device+0xc8/0x118 [DD601E40] [C0140488] bus_for_each_drv+0x5c/0xa4 [DD601E70] [C0140EF8] device_attach+0x98/0xb0 [DD601E90] [C014050C] bus_add_device+0x3c/0x148 [DD601EB0] [C013EF68] device_add+0x10c/0x174 [DD601ED0] [C0142F88] platform_device_add+0x158/0x1c8 [DD601EF0] [C01431A8] platform_device_register_simple+0x40/0x8c [DD601F10] [E906C374] alsa_card_pmac_init+0x40/0x9c [snd_powermac] [DD601F20] [C004328C] sys_init_module+0x1cc/0x2ec [DD601F40] [C000CFD4] ret_from_syscall+0x0/0x38 --- Exception: c01 at 0xff3f948 LR = 0x10002494 Instruction dump: 80010044 38210040 7c0803a6 4e800020 7c0802a6 9421ffc0 98a10010 7c691b78 7c872378 38c00000 90010044 39000002 a0890004 39210010 80630008 The content of /proc/cpuinfo: processor : 0 cpu : 750FX temperature : 38 C (uncalibrated) clock : 700.000000MHz revision : 2.2 (pvr 7000 0202) bogomips : 49.53 timebase : 24835245 machine : PowerBook4,3 motherboard : PowerBook4,3 MacRISC2 MacRISC Power Macintosh detected as : 257 (iBook 2 rev. 2) pmac flags : 0000001b L2 cache : 512K unified pmac-generation : NewWorld ---------------------------------------------------------------------- Johannes Berg - 04-03-06 08:54 ---------------------------------------------------------------------- You have to load i2c-powermac first.
