I've booted with debug turned on and did not see anything special. I've got a dump of dmesg with acpi.debug_layer=0xffff acpi.debug_level=0xfffff. I won't attach it unless someone specifically requests it. It is huge.
On the other hand, here is something which I had not paid attention to before (this appears in the dmesg even without acpi debugging turned on): [ 31.206919] ata2.00: ACPI cmd 00/00:00:00:00:00:b0 rejected by device (Stat=0 x51 Err=0x04) [ 31.207895] ata2.00: ACPI cmd ef/10:01:00:00:00:b0 rejected by device (Stat=0 x51 Err=0x04) [ 31.208136] ata2.00: ACPI cmd ef/10:02:00:00:00:b0 rejected by device (Stat=0 x51 Err=0x04) [ 31.208212] ata2.00: ACPI cmd ef/10:03:00:00:00:b0 filtered out [ 31.208444] ata2.00: ACPI cmd ef/10:04:00:00:00:b0 rejected by device (Stat=0 x51 Err=0x04) [ 31.208684] ata2.00: ACPI cmd ef/10:05:00:00:00:b0 rejected by device (Stat=0 x51 Err=0x04) This is the kernel executing the drive's GTF. You can see the 4th command is filtered out by the kernel (i.e. it is not sent to the drive). I turned filtering off and found that the filtered command was the only command which the drive accepted. But even with filtering off, I was not able to resume. I eventually removed the hard drive and booted from a USB stick but still was not able to resume. I also tried acpi_power=s3_beep and did not hear any beep. (But I'm having a nagging doubt that there may not be a real *legacy* pc-speaker- style hardware on the laptop. I can't get the darn thing to beep when I'm booted in single user mode.) -- resume from suspend doesn't work (powers off instead) for Acer Timeline 3810t https://bugs.launchpad.net/bugs/405120 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
