deeks9000: 1) Regarding the BIOS Error, you are welcome to update your BIOS to see if this provides resolution.
2) The next step is to fully commit bisect from kernel 4.13 to 4.15 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions, or providing a commit from a kernel version bisect is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Tags added: kernel-bug-exists-upstream needs-bisect ** Summary changed: - Long boot time (approx 5 minuntes!), long shutdown + [Compaq Presario A900 Notebook PC] ~5 minutes to boot or shutdown -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1767356 Title: [Compaq Presario A900 Notebook PC] ~5 minutes to boot or shutdown Status in linux package in Ubuntu: Incomplete Bug description: SCENARIO: I have just upgraded to 18.04 from 17.10 PROBLEM PACKAGE (?): linux-modules-4.15.0-20-generic REPORT FROM 'dmesg' shows this typical error: [ 899.040146] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:41:pipe B] flip_done timed out [ 909.280160] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [PLANE:35:plane B] flip_done timed out BASIC DETAILS: 'flip_done' timed out does not sound good to me! Is this the reason for the extremely long boot time observed? Approximate boot time is 5 minutes! Long delays on shutdown also. The new system works great once it is up and running! My laptop is 10 years old (Comapaq Presario A900), but it has worked well with Ubuntu over the years and I was hoping that the 18.04 would have a *faster* boot time, so I was excited to install the new system. Alas, it now suffers from excessively long boot time which I am convinced is due to a timeout error. But I do not have enough knowledge to know exactly what exactly is 'timing out'?
