Hello, I have a Compaq Evo N620c laptop and at the moment I'm running 5.4-STABLE on it. But that doesn't go well :( When booting with acpi enabled is totaly hangs after this: acpi_cmbat1: battery initialization failed, giving up acpi_acad0: acline initialization start acpi_acad0: acline initialization done, tried 1 times Then I have to power down the laptop and run fsck in single user mode, but also that go's wrong. After a minute or so it's spewing out this: ad0: WARNING - READ_DMA interrupt was seen but timeout fired LBA=8765883 And that several times. I never comes out of this and again I have to power it down. With an old kernel 5.2.1 I can go in single user mode and run fsck on the disk. When I boot with acpi disabled, everything seems to be okay and I can compile what I want, never a lock up. I have attached 2 logs. In the first you can see what happens if I boot (verbose) with acpi enabled. The second log shows what happens when I go in single user mode. Regards, Richard. -------------- next part -------------- A non-text attachment was scrubbed...
