11 Lines of Kernel Code?

[Chime Hart]

Hi All Last Friday evening I traded messages on this list with 
Samuel-and-others about my console hang or lockup. Reviewing again, on 
this laptop running a Debian Sid 5.9.0.1 with Voxin. Multiple times when 
attempting to paste in an article, nothing was inserted, but I got tons of 
errors, which you will see in this small extract. Cut-and-paste still 
works on my desktop machine, same kernel, but with a DecTalk, still with a 
4second delay. Here is a sampling of kernel.log, where we see each time 
speakup is mentioned, also these errors beginning with 3thousand are after 
pasting.

Oct 23 18:44:28 dance kernel: [ 3021.909090] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Back again live. Other than the flat review, I think cut-and-paste are the 
Speakup items I use the most. Thanks in advance for any analysis. After my 
console got hung, I booted, thinking that would have fixed it.
