cat /proc/interrupts

[kantal]

Hi!

In Olimex Debian images for A20, release 8 and 10
cat /proc/interrupts
hangs and dmesg shows:   cat[2461] exited with preempt_count 1

cp /proc/interrupts ~
hangs, too.

Any suggestions?

[Gerrit]

no suggestions same effect here, but the first time i try it i get a lot off messages, and the second time it just hangs

Code Select Expand

cat /proc/interrupts

Maybe this is of some help to find the reason

I just noticed it was reported before https://www.olimex.com/forum/index.php?topic=3981.0
