I know how to run dmesg but not how to interpret the output.
I installed Slackware64-15.0 on the ThinkPad X200 last week. Each time I turn it on it booted and started the OS very quickly, just as it had done with multiple prior versions of Slackware64. But, ... Yesterday, the ThinkPad X200 paused during startup at a line related to ntpd. The same line at which the Dell Latitude E5410 paused after booting/starting quickly before then. Two different brands, CPUs, chipsets. Suddenly each paused starting the OS and continued to pause every time after that. While the Dell's been replaced I want to find why this happens so the ThinkPad returns to quickly starting and available for logging in. I ran dmesg -T and redirected output to a file, dmesg-x200.txt. That file's been uploaded to fileconvoy.com <https://tinyurl.com/3fa234eb> and I need help understanding what changed from quick, complete booting/starting to the delay. Looking at lines 838-839 you'll see a 6.5 minute delay: [Fri Mar 4 07:49:30 2022] random: 7 urandom warning(s) missed due to ratelimiting [Fri Mar 4 07:55:50 2022] usb 2-1: new high-speed USB device number 2 using ehci-pci Searching the file for anything related to ntp found nothing, but that's where it stalled. Also no 'error' and only one 'warning': [Fri Mar 4 07:49:21 2022] ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Pm1aControlBlock: 16/32 (20210730/tbfadt-564) [Fri Mar 4 07:49:21 2022] ACPI BIOS Warning (bug): Invalid length for FADT/Pm1aControlBlock: 32, using default 16 (20210730/tbfadt-669) I know nothing about the kernel so I cannot interpret the output to find the reason for the problem. If there are other resources where I should ask for help please point me to them. TIA, Rich
