Description Ferenc Wágner 2011-01-03 10:49:02 UTC

After yanking out my USB-to-serial converter cable (ark3116), I was presented with the attached BUG. I've never seen such a thing yet (after running 2.6.36 for quite some time). The issue isn't trivially reproducible.

Is this still an issue on 2.6.38-rc7?

Comment 3 Ferenc Wágner 2011-03-07 19:04:50 UTC

I haven't hit it since then, unless it's the same memory corruption problem that I filed as bug 26582.

Comment 4 Florian Mickler 2011-03-29 20:49:52 UTC

Ok, I'm closing this one as unreproducible. If you see it again, please reopen.

Thx,
Flo
