Title:
I/O performance problems with kernel 3.15.x
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I'm using Ubuntu 14.10 dev with linux-image-generic 3.15.0.5.6 and after the
kernel 3.15.x was installed I noticed some I/O problems after a reboot. I'm
noticing that now on every boot my hard disk will stop multiple times for a
short time and logging out from the console does sometimes hang a few seconds.
