Description

Hi everyone,

I encountered strange behaviour when using ZFS. Everytime there is I/O from / to ZFS, it seems to mangle my DVB stream.

zpool status:
pool: tank
state: ONLINE
scan: scrub repaired 0 in 8h30m with 0 errors on Mon Dec 17 21:01:42 2012
config:

NAME                                         STATE     READ WRITE CKSUM
    tank                                         ONLINE       0     0     0

If I do a write to the zpool (downloading with 5 Mb/s is sufficient), TVHeadend floods with the following errors regardless of the tuned frequency and with 100% reception:

AFAICT, tvheandend doesn't buffer on the pool and testing with massive I/O on my root partition (ext4), I can't reproduce the errors.

Is this a bug in ZFS/SPL or in TVHeadend?
