It's specifically BTRFS related, I was able to reproduce it on a bare
drive (no lvm, no md, no bcache). It's not bad RAM, I was able to
reproduce it on multiple machines running either 3.17 or late RCs.
I've tested 3.18-rc2 for about 2 hours now, can't get any failures, so
that's good. If anyone
The following code reliably throws a SIGBUS in the memset, and cat
testfile > /dev/null returns an IO error.
I've sometimes gotten as high as iteration 900 before a SIGBUS, so
don't assume a single clear is OK.
linux 3.17.0, SATA -> MD(raid5) -> bcache (ssd) -> btrfs
Working on eliminating more
I'm in the middle of debugging the exact same thing. 3.17.0 -
rtorrent dies with SIGBUS.
I've done some debugging, the sequence is something like this:
open a new file
fallocate() to the final size
mmap() all (or a portion) of the file
write to the region
run SHA1 on that mmap'd region to validat
