I think, the 2.6.25 kernel has this issue as well: [17181797.575125] irq 19: nobody cared (try booting with the "irqpoll" option) [17181797.575125] Pid: 0, comm: swapper Tainted: G W 2.6.25-1-generic #1 [17181797.575125] [17181797.575125] Call Trace: [17181797.575125] <IRQ> [<ffffffff8027c94e>] __report_bad_irq+0x1e/0x80 [17181797.575125] [<ffffffff8027cc4e>] note_interrupt+0x29e/0x2d0 [17181797.575125] [<ffffffff8027d74d>] handle_fasteoi_irq+0x9d/0x100 [17181797.575125] [<ffffffff8020f67c>] do_IRQ+0x7c/0x100 [17181797.575125] [<ffffffff8020c9dd>] ret_from_intr+0x0/0x19 [17181797.575125] <EOI> [<ffffffff80220cb0>] hpet_legacy_next_event+0x0/0x50 [17181797.575125] [<ffffffffa002b502>] :processor:acpi_idle_enter_simple+0x18a/0x1fc [17181797.575125] [<ffffffffa002b125>] :processor:acpi_idle_enter_bm+0xc8/0x31b [17181797.575125] [<ffffffff803d67a8>] cpuidle_idle_call+0xc8/0x120 [17181797.575125] [<ffffffff803d66e0>] cpuidle_idle_call+0x0/0x120 [17181797.575125] [<ffffffff803d66e0>] cpuidle_idle_call+0x0/0x120 [17181797.575125] [<ffffffff8020b420>] default_idle+0x0/0x50 [17181797.575125] [<ffffffff8020aed2>] cpu_idle+0x52/0xe0 [17181797.575125] [<ffffffff80211470>] pda_init+0x30/0xb0 [17181797.575125] [17181797.575125] handlers: [17181797.575125] [<ffffffffa008d820>] (usb_hcd_irq+0x0/0x60 [usbcore]) [17181797.575125] Disabling IRQ #19
Another warning which is probably unrelated because it is about powermanagement, as far as I can see, is the following: [17181791.410157] ------------[ cut here ]------------ [17181791.410157] WARNING: at /build/buildd/linux-2.6.25/drivers/base/power/main.c:77 device_pm_add+0x6a/0x100() [17181791.410157] Modules linked in: ppp_deflate zlib_deflate bsd_comp ppp_async crc_ccitt ppp_generic slhc rfcomm l2cap hci_usb bluetooth i915 drm binfmt_misc ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 xt_state nf_conntrack ipt_REJECT xt_tcpudp bridge ppdev ipv6 container sbs sbshc acpi_cpufreq cpufreq_powersave cpufreq_stats cpufreq_userspace cpufreq_ondemand cpufreq_conservative freq_table iptable_filter ip_tables x_tables ext2 mbcache uinput sbp2 parport_pc lp parport snd_hda_intel snd_seq_dummy pcmcia snd_seq_oss snd_seq_midi snd_pcsp yenta_socket psmouse cfg80211 rsrc_nonstatic snd_rawmidi snd_seq_midi_event serio_raw sdhci pcmcia_core snd_pcm_oss snd_mixer_oss mmc_core snd_seq ac snd_pcm iTCO_wdt iTCO_vendor_support battery snd_timer snd_seq_device bay video output snd shpchp pci_hotplug soundcore snd_page_alloc button intel_agp thinkpad_acpi led_class nvram evdev reiserfs sha256_generic aes_x86_64 aes_generic cbc sg sd_mod ata_piix ide_pci_generic ide_core ata_generic ohci1394 ieee1394 pata_acpi ehci_hcd uhci_hcd libata usbcore scsi_mod dock dm_crypt dm_mod crypto_blkcipher thermal processor fan fbcon tileblit font bitblit softcursor fuse [last unloaded: e1000e] [17181791.410157] Pid: 2293, comm: khubd Not tainted 2.6.25-1-generic #1 [17181791.410157] [17181791.410157] Call Trace: [17181791.410157] [<ffffffff80239084>] warn_on_slowpath+0x64/0xa0 [17181791.410157] [<ffffffff8023a14e>] printk+0x4e/0x60 [17181791.410157] [<ffffffff802ca548>] ifind+0x48/0xc0 [17181791.410157] [<ffffffff8030bb2a>] sysfs_create_link+0xaa/0x120 [17181791.410157] [<ffffffff803bf4f1>] bus_add_device+0x151/0x190 [17181791.410157] [<ffffffff803c3b0a>] device_pm_add+0x6a/0x100 [17181791.410157] [<ffffffff803be0c3>] device_add+0x463/0x610 [17181791.410157] [<ffffffffa008a7a3>] :usbcore:usb_new_device+0x63/0xb0 [17181791.410157] [<ffffffffa008bfde>] :usbcore:hub_thread+0x74e/0xef0 [17181791.410157] [<ffffffff8024eb40>] autoremove_wake_function+0x0/0x30 [17181791.410157] [<ffffffffa008b890>] :usbcore:hub_thread+0x0/0xef0 [17181791.410157] [<ffffffff8024e71b>] kthread+0x4b/0x80 [17181791.410157] [<ffffffff8020d498>] child_rip+0xa/0x12 [17181791.410157] [<ffffffff8024e6d0>] kthread+0x0/0x80 [17181791.410157] [<ffffffff8020d48e>] child_rip+0x0/0x12 [17181791.410157] [17181791.410157] ---[ end trace c5221687c6eac71e ]--- [17181791.410158] usb 1-2: configuration #1 chosen from 1 choice As a side-note: The 2.6.25 kernel brakes my WLAN: [EMAIL PROTECTED]:~$ sudo modprobe iwl4965 WARNING: Error inserting iwlwifi_mac80211 (/lib/modules/2.6.25-1-generic/ubuntu/wireless/iwlwifi/mac80211/compatible/net/mac80211/iwlwifi_mac80211.ko): Invalid module format FATAL: Error inserting iwl4965 (/lib/modules/2.6.25-1-generic/ubuntu/wireless/iwlwifi/iwlwifi/compatible/iwl4965.ko): Invalid module format [EMAIL PROTECTED]:~$ dmesg [17181918.272960] rfcomm_tty_ioctl: TIOCGSERIAL is not supported [17182481.788864] iwlwifi_mac80211: version magic '2.6.25-1-generic SMP mod_unload ' should be '2.6.25-1-generic SMP mod_unload modversions ' [17182481.791616] iwl4965: version magic '2.6.25-1-generic SMP mod_unload ' should be '2.6.25-1-generic SMP mod_unload modversions ' I am attaching the dmesg for reference.
