Public bug reported: System : Dell Latitude D810, Karmic with latest updates as of now. The system freezes rather frequently when either plugging/unplugging the DC adapter, or resuming from suspend. When frozen, the HDD led stays lit.
* When the freeze occurs after resuming from suspend, it often results in a hard lock (magic SysReq keys have no effect). Sometimes, though, it just freezes for around 30s-1min, and then unfreezes. In these cases, pressing the caps lock/num lock keys correclty affect the indicator leds. In these cases, I usually find messages like this in the syslog: Jul 13 17:15:36 tadzim kernel: [ 4025.000165] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen Jul 13 17:15:46 tadzim kernel: [ 4025.000189] ata1.00: cmd c8/00:08:9e:11:af/00:00:00:00:00/e0 tag 0 dma 4096 in Jul 13 17:15:46 tadzim kernel: [ 4025.000193] res 40/00:80:00:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) Jul 13 17:15:46 tadzim kernel: [ 4025.000201] ata1.00: status: { DRDY } Jul 13 17:15:46 tadzim kernel: [ 4030.040181] ata1: link is slow to respond, please be patient (ready=0) Jul 13 17:15:46 tadzim kernel: [ 4035.024183] ata1: device not ready (errno=-16), forcing hardreset Jul 13 17:15:46 tadzim kernel: [ 4035.024275] ata1: soft resetting link Jul 13 17:15:46 tadzim kernel: [ 4035.206724] ata1.00: configured for UDMA/100 Jul 13 17:15:46 tadzim kernel: [ 4035.206746] ata1: EH complete * When the freeze occurs when plugging in the DC adapter, parts the desktop are responsive, apps that are already loaded continue working, however anything that involves disk activity hangs. Today I had a console open when it occurred, and I got these results: - dmesg yields a Bus Error - hdparm --verbose /dev/sda gives this (I took a picture of the screen and transcribe it here...): /de/sda outgoing cdb: 85 08 2e 00 00 00 00 00 00 00 00 00 00 40 ec 00 SG_IO: ATA_16 status=0x0, host_status=0x4, driver_status=0x0 SG_IO: bad response (not CHECK_CONDITION) outgoing cdb: 85 08 2e 00 00 00 00 00 00 00 00 00 00 40 a1 00 SG_IO: ATA_16 status=0x0, host_status=0x4, driver_status=0x0 SG_IO: bad response (not CHECK_CONDITION) HDIO_DRIVE_CMD(identify) failed: Invalid exchange IO_support = 0 (default) readonly = 0 (off) readahead = 6144 (on) geometry = 19457/255/63, sectors = 312581808, start = 0 Note that these problems also occured with Jaunty, but less frequently it seems. Please tell me how I can help debugging it. ** Affects: ubuntu Importance: Undecided Status: New -- [Karmic] Frequent freeze on Dell D810 https://bugs.launchpad.net/bugs/399054 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
