Package: linux-2.6 Version: 2.6.33-1~experimental.4 Severity: normal Tags: experimental
Firstly, please note that I'm running this inside a Qemu, but I imagine that it should not change things much. I installed 2.6.33 to try out the new improvements regarding network namespaces, and while creating and killing hundreds of them, I got many warnings from the kernel that might indicate a bug somewhere. Please see the log already included by reportbug. -- Package-specific info: ** Version: Linux version 2.6.33-2-amd64 (Debian 2.6.33-1~experimental.4) ([email protected]) (gcc version 4.3.4 (Debian 4.3.4-8) ) #1 SMP Wed Mar 17 18:41:49 UTC 2010 ** Command line: BOOT_IMAGE=/boot/vmlinuz-2.6.33-2-amd64 root=UUID=195c18a2-eda7-40b8-8748-381999d6c854 ro quiet ** Tainted: W (512) * Taint on warning. ** Kernel log: [ 6696.034566] ---[ end trace ef7b93cb006e989d ]--- [ 6696.035331] ------------[ cut here ]------------ [ 6696.035334] WARNING: at /build/mattems-linux-2.6_2.6.33-1~experimental.4-amd64-ieqSsa/linux-2.6-2.6.33-1~experimental.4/debian/build/source_amd64_none/kernel/sysctl.c:1894 unregister_sysctl_table+0xa6/0xd1() [ 6696.035336] Hardware name: [ 6696.035337] Modules linked in: veth loop parport_pc parport snd_pcm tpm_tis evdev snd_timer i2c_piix4 tpm tpm_bios button processor serio_raw i2c_core snd soundcore snd_page_alloc pcspkr psmouse ext3 jbd mbcache sg sr_mod cdrom sd_mod crc_t10dif ata_generic ata_piix libata floppy 8139cp thermal thermal_sys 8139too mii scsi_mod [last unloaded: veth] [ 6696.035354] Pid: 9, comm: netns Tainted: G W 2.6.33-2-amd64 #1 [ 6696.035355] Call Trace: [ 6696.035357] [<ffffffff8104e303>] ?
