Adding relevant CCs. Original message follows. ============== Hi, See the screenshot at http://apt.niif.hu/ipw_oops.png. During bootup, initramfs-tools tried to load the ipw2200 module, but nobody fed it the necessary firmware, so request_firmware timed out and the module unload cleanup oopsed in device_pm_remove: void device_pm_remove(struct device *dev) { pr_debug("PM: Removing info for %s:%s\n", dev->bus ? dev->bus->name : "No Bus", kobject_name(&dev->kobj)); mutex_lock(&dpm_list_mtx); list_del_init(&dev->power.entry); mutex_unlock(&dpm_list_mtx); pm_runtime_remove(dev); } 00000a0a <device_pm_remove>: a0a: 55 push %ebp a0b: 89 e5 mov %esp,%ebp a0d: 53 push %ebx a0e: 89 c3 mov %eax,%ebx a10: b8 08 00 00 00 mov $0x8,%eax a15: e8 fc ff ff ff call a16 <device_pm_remove+0xc> a1a: 8d 4b 5c lea 0x5c(%ebx),%ecx a1d: 8b 53 5c mov 0x5c(%ebx),%edx a20: 8b 43 60 mov 0x60(%ebx),%eax a23: 89 42 04 mov %eax,0x4(%edx) a26: 89 10 mov %edx,(%eax) a28: 89 4b 5c mov %ecx,0x5c(%ebx) a2b: 89 4b 60 mov %ecx,0x60(%ebx) a2e: b8 08 00 00 00 mov $0x8,%eax a33: e8 fc ff ff ff call a34 <device_pm_remove+0x2a> a38: 89 d8 mov %ebx,%eax a3a: e8 fc ff ff ff call a3b <device_pm_remove+0x31> a3f: 5b pop %ebx a40: 5d pop %ebp a41: c3 ret The offending IP translates to line a23, so the problem is edx being 0 at that point. I'm not sure which struct device field has offset 0x5c, maybe power, but I'm lost at this point anyway. I don't know whether it's a new bug or not, never did such insane things previously. rmmod ipw2200 definitely worked under 2.6.31, and it's possible that it works under 2.6.32-rc4 too, I forgot to check that (but will do so tonight). -- Regards, Feri. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
