Date: Fri, 14 Sep 2012 13:34:01 +0200 [thread overview]
Message-ID: <50531629.9020107@ahsoftware.de> (raw)
Hello,
I'm currently experiencing some major problems trying to do a full
backup. I've recently added an USB 3.0 card to my system and now it
seems my full-backup routine evolved to a stress test. ;)
What I'm doing is either
tar cp . | mbuffer | bzip2smp >foo.tar.bz2
or
dd if=/dev/sdaN bs=4M | mbuffer | bzip2smp >foo.img.bz2
bzip2smp spawns 7 threads on this machine (an intel Core i7 860 @
2.80GHz) with HT enabled, which really seems to stress the HW (I get
various throttling events).
Source is an SSD, target an USB 3.0 disk.
Besides a problem with USB 3.0 which just manifest in those 4 message:

(that tainted is through fglrx)
I haven't looked at the source in the kernel and because I'm not
familiar with the involved code, I thought I just paste that error here
before trying if I can find the problem myself.
I had that error more than once, so it looks like I can reproduce it. If
I can help more with logs or similiar, just ask.
Regards,
Alexander
