I see this when using gjournal too.
I suspect the timeout on the flush cache command needs to be increased.
I haven't got around to testing it but you could try increasing the
timeout in ata-disk.c (around line 280) ->
request->u.ata.lba = 0;
request->u.ata.count = 0;
request->u.ata.feature = 0;
request->bytecount = 0;
request->transfersize = 0;
request->timeout = 1;
request->retries = 0;
request->flags = ATA_R_CONTROL;
request->u.ata.command = ATA_FLUSHCACHE;
