Actually it didn't even get that far. The backtrace is:
#0  0x40120264 in __llseek (fd=4, offset=952422534144, whence=0)

And the variables in xlog_find_tail: (this is not the initial values,
but the data after running a while)
2: *log = {l_tail_lsn = 1555200034, l_last_sync_lsn = 8869107466752,
  l_mp = 0x0, l_dev = 0, l_logBBstart = 580635924371603456,
  l_logsize = -1303633567, l_logBBsize = 1683758742, l_curr_cycle = 658578423,
  l_prev_cycle = 1930723645, l_curr_block = -1629678499,
  l_prev_block = 1488263099, l_iclog_size = 859122733,
  l_iclog_size_log = -1462469193, l_iclog_bufs = 827354497,
  l_grant_reserve_cycle = 1914757874, l_grant_reserve_bytes = -1837674487,
  l_grant_write_cycle = 499151154, l_grant_write_bytes = 903190826}

3: *head_blk = 970809832858919324

4: *tail_blk = 4612568755539746816

Now, that doesn't really tell me anything, but hopefully someone that
know xfs better will be able to tell if this looks right or not? The
filesystem is ~ 0.8 TB, btw.

And it's still going.... (now it has been running for 15 hours)
