Re: [Bugme-new] [Bug 12785] New: kswapd block the whole system by IO blaster in some case

[陈世昊 <crackevil@gmail.com>]

Those experimental packages have been in use for 2 months, this issue
just occured and just once.
I think it's quite unexpectly random. Even in the same environment, I
can't make that issue alive again.

Today I'll look through the logs. Maybe in the syslog I can find
something valuable while other logs like dmesg, messages, kern.log,
etc have been found useless.
