Summary: linux-image-2.6.38-2-686 (Debian): Horrible Time Skew, Eventual Near-zero Responsiveness Product: ACPI Version: 2.5 Kernel Version: 2.6.39-rc6 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Other AssignedTo: acpi_ot...@kernel-bugs.osdl.org ReportedBy: mail-sender-e53...@sabahattin-gucukoglu.com CC: b...@decadent.org.uk Regression: Yes Created an attachment (id=59292) --> (https://bugzilla.kernel.org/attachment.cgi?id=59292) Debian bug tracker log mailbox for #626427 This is initially basically a forward of Debian bug #626427 whose log can be found here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626427 (Also attached as plaintext mailbox.) The braille display is away for now, but it still managed to freeze after a while longer without BRLTTY running. This is using 2.6.39 RC6. In summary, the system will slow right down after an unspecified time, but more frequently with BRLTTY running, it seems. Touching a backspace at an empty shell line will result in a continuous beeping from the system speaker without pause, but dnscache still serves data, even if no process or thread will start. It will require a hard reset to make the system be usable again. The other important manifestation is horrible clock drift. It looks like a regression from 2.6.32 in the acpi_pm clocksource driver. The clocksource selected automatically was tsc, though, after the kernel upgrade; it was acpi_pm before then in 2.6.32, giving 0.13s drift, which I suppose is acceptable on my hardware. Now it's somewhere like 500s behind at every update on tsc, and less drastic but unusable back-and-forth with acpi_pm. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ vRanger cuts backup time in half-while increasing security.
