Package: nvidia-kernel-2.6.32-5-amd64 Version: 195.36.31+1+2+2.6.32-20 Severity: important
Hi, I'm assigning to nvidia-kernel-* because it fits most closely where the error occurs. Sorry if I'm wrong, just reassign to some other kernel (or related) package if appropriate. I'm using a desktop system with nvidia X11 drivers and serial ports on a multiple USB-to-serial(8x) adapter. While I'm sending character lines to serial ports (e.g. /dev/ttyUSB1 and /dev/ttyUSB4), my script outputs this via a gnome terminal, which is _scrolling fast_ (I think this is related to the problem). This way, I get the following backtrace in dmesg after a while (with squeeze default kernel on amd64): [ 2707.204525] ------------[ cut here ]------------ [ 2707.204542] WARNING: at /build/buildd-linux-2.6_2.6.32-22-i386-Nf7Z7O/linux-2.6-2.6.32/debian/build/source_i386_n one/drivers/usb/serial/usb-serial.c:406 serial_write_room+0x53/0x6a [usbserial]() [ 2707.204545] Hardware name: HP Compaq dc5800 Microtower [ 2707.204547] Modules linked in: acpi_cpufreq cpufreq_stats cpufreq_userspace cpufreq_conservative ip6table_filter cpufreq_powersave ip6_tables iptable_filter ppdev lp sco rfcomm bnep l2cap crc16 bluetooth rfkill kvm_intel binfmt_misc kvm nls_utf8 cifs nfsd exportfs nfs lockd fscache nfs_acl auth_rpcgss sunrpc tun ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 ip_tables x_tables fuse loop snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_seq snd_timer snd_seq_device snd soundcore snd_page_alloc nvidia(P) parport_pc ftdi_sio pcspkr usbserial button parport evdev wmi i2c_core psmouse processor serio_raw ext3 jbd mbcache dm_mod sg sr_mod cdrom sd_mod crc_t10dif ata_generic uhci_hcd ehci_hcd thermal ata_piix floppy r8169 mii libata thermal_sys scsi_mod e1000e usbcore nls_base [last unloaded: scsi_wait_scan] [ 2707.204606] Pid: 10, comm: events/1 Tainted: P 2.6.32-5-amd64 #1 [ 2707.204608] Call Trace: [ 2707.204614] [<ffffffffa021b760>] ?

When I leave X11 running, but run my script from another virtual console, the above traces don't show up but serial output gets corrupted anyway. Thanks for considering.
