Hello, On new Lenovo T440p laptops with new BIOSes (1.16 and further) there is a memory corruption when trying to disable, and then re-enable, nvidia GPU. There is a bugreport for bbswitch ( https://github.com/Bumblebee-Project/bbswitch/issues/78), but this problem shows even when doing disable and re-enable with acpi_call,...

...atform module Support for these modules, as for the network (Ethernet + WiFi) for RHEL/Centos6. I tested Lenovo W540, and the WiFi is not detected. lspci shows: 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 818b I came across http://askubuntu.com/questions/376732/thinkpad-t440p-wireless-network-controller, so it turns out, this WiFi card is not supported (yet). So, if anyone can recommend a working solution, please contact me, either here or off the list. Thanks in advance,

Use syslinux 6.03 for my g4l disk imaging project, and it works great. Have just had a user that has a new thinkpad t440p system and it load the syslinux, and he can select any of the various kernels included on the iso, but it freezes at a point with no error message just stops? Originally, the last thing ata8: PATA max PIO4 cmd 0x170 ctl 0x376 irq 15 But I built a special kernel with all the PATA stuff removed si...

What's the connector name when you plug in via, say, DVI? Is it "DP-1" or is it "DVI-D-1" or whatever? You should be able to see the name in 'xrandr'. Unfortunately I don't know how the T440p is wired, there are a few ways it could go. In some cases, even the "VGA" port is secretly a DP -> VGA active adapter inside the laptop. Basically I'm trying to rule DisplayPort as a source of potential issues. -ilia On Tue, Jun 18, 2019 at 4:12 PM Harald Harders <harald.ha...

...65M). Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi debugger trace) and stop using the DSM functions for D3cold when power resources are available on the parent PCIe port. pci_d3cold_disable() is not used because on some machines, the old DSM method is broken. On a Lenovo T440p (GT 730M) memory and disk corruption would occur, but that is fixed with this patch[2].

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). See the first version[1] for a background on the fixed problems. This is the second revision of incorporating feedback from Emil Velikov (patch 1), Mika Westerberg (patch 4).

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). These are the final patches targeting v4.8. Changes compared to v2[1]: collected R-b from Hans and Mika and fixed a minor comment style issue. I recommend it to be merged before
