I would very to say: "Yes it works" like make me falsely guess this test on a
d380 with an disk connected to ncr53c720 hba:
# CNT=0; while true; do nice -n -5 tar -xslpf linux-2.6-trace.tar; nice -n -5
rm -rf linux-2.6-trace; CNT=$(($CNT + 1)); echo "CNT=$CNT"; date; done
it run several hours without issue, till console shows me again a failure in
the fs:
#CNT=1
#Mon Mar 10 12:33:54 CET 2008
#CNT=2
#Mon Mar 10 12:35:14 CET 2008
#CNT=190
#Mon Mar 10 16:32:29 CET 2008
#CNT=191
#Mon Mar 10 16:33:44 CET 2008
But again same kind of error:
#EXT3-fs error (device sdb9): ext3_readdir: bad entry in directory #99187:
rec_len % 4 != 0 - offset=0, inode=1953393
#EXT3-fs warning (device sdb9): empty_dir: bad directory (dir #99187) - no `.'
or `..'
Note that the 53c710 of the external drive didn't shows much better results:
#scsi3: (3:0) phase mismatch at 01e8, phase IO CD MSG BSY REQ MSG IN
#scsi3: Bus Reset detected, executing command 1fe1f2c0, slot 1fe388a4, dsp
003781e8[01e8]
# failing command because of reset, slot 1fe388a4, cmnd 1fe1f2c0
just during a dist-upgrade.
Sorry,
