I have the same symptoms on Kubuntu Lucid, amd64, kernel "2.6.32-22-generic #33-Ubuntu SMP". I also have an Asus K8V Deluxe motherboard, with a Promise "PDC20378 (FastTrak 378/SATA 378) (rev 02)" (according to lspci) SATA controller.
Suspending once works. After resume, everything seems fine. The following message appears in "kern.log" at resume (identical timestamps snipped): May 16 08:57:37 chade kernel: [23999.040031] ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen May 16 08:57:39 chade kernel: [23999.040038] ata6.00: failed command: READ DMA EXT [23999.040045] ata6.00: cmd 25/00:08:c0:ee:dc/00:00:39:00:00/e0 tag 0 dma 4096 in [23999.040047] res 40/00:ff:00:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) [23999.040050] ata6.00: status: { DRDY } [23999.040057] ata6: hard resetting link [23999.550041] ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [23999.621420] ata6.00: configured for UDMA/133 [23999.621425] ata6.00: device reported invalid CHS sector 0 [23999.621430] ata6: EH complete If I, later, try to suspend again, the screen goes black, but the computer does not turn off; after several minutes the screen comes back on at the console, where this message is displayed: PM: some devices failed to suspend: error 13421773034217730 ata6.00: status { DRDY } ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata6.00: failed command: STANDBY IMMEDIATE ata6.00: cmd e0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 res 40/00:ff:00:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) (copied by hand, typos possible). It sat there for at least 20 minutes. The machine was not responsive to any key combos or the soft-off button, so eventually I had to "hard-off." -- Suspend only works once, dmesg shows errors about sata disk https://bugs.launchpad.net/bugs/510246 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
