Hello.
I did a stock install of 6.1-RELEASE yesterday and I noticed something
weird. Whenever I switched the virtual console to a different screen,
it would take almost 2 whole seconds before switching. At first I
thought it was IRQ related since it was happening during the heavy disk
activity of an install, but I noticed the same behavior after rebooting
the machine.
I csup'd to RELENG_6 as of last night and that didn't help. One thing
I did notice is that the whole kernel seems to "pause" during the two
second switching operation-- I noticed this because I switched virtual
screens during a bg fsck and each time I switched, the ATA light would
turn off during the duration and come back on immediately after the
console switched. This behavior is 100% repeatable for me. I looked at
"systat -vms" and top(1) but didn't notice anything out of the ordinary.
This only seems to affect this one system; my other machines switch
virtual screens instantly. This happened both with GENERIC and SMP
kernels.. I'll include the latest dmesg below. Nothing else appeared
in any logs. I can provide a verbose dmesg if necessary.
The only thing I can think of is that I'm using kbdmux with no PS/2
keyboard attached-- but I'm using a similar USB keyboard on another
6.1-STABLE box just fine. Any ideas?
