Re: [9fans] usbd error message

[Bela Valek <bvalek2@gmail.com>]

First of all, i missed some pids, the total number of usbd processes is 8:

glenda            5    0:00   0:00      356K Sleep    usbd
glenda            6    0:00   0:00      356K Pread    usbd
glenda            7    0:00   0:00      356K Rendez   usbd
glenda            8    0:00   0:00      356K Rendez   usbd
glenda           95    0:00   0:00      356K Sleep    usbd
glenda           96    0:00   0:00      356K Pread    usbd
glenda           97    0:00   0:00      356K Rendez   usbd
glenda           98    0:00   0:00      356K Rendez   usbd

processes 5 - 8 give this an output like this:

term% echo 'stacks()' | acid -l thread 5
/proc/5/text:386 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/386
/sys/lib/acid/thread:1: (error) pushfile:
/sys/src/libthread/sched.acid: '/sys/src/libthread/sched.acid' does
not exist
no symbol information
acid: <stdin>:2: (error) no function stacks
acid:
echo kill > /proc/5/ctl

processes 95 - 98 give this output (missing line: 'no symbol information'):

term% echo 'stacks()' | acid -l thread 95
/proc/5/text:386 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/386
/sys/lib/acid/thread:1: (error) pushfile:
/sys/src/libthread/sched.acid: '/sys/src/libthread/sched.acid' does
not exist
acid: <stdin>:2: (error) no function stacks
acid:
echo kill > /proc/95/ctl
