Hi Darrick, We can duplicate the problem here. The aic94xx with V28 passed IO testing overnight if we apply IO directly to /dev/sd?. But it fails very quickly when we create a partition and format it as ext3. The V17 sequencer works fine with both cases. We are looking into it and find the root cause ASAP. Thanks!

FWIW, v17 looks good for both SAS/SATA load testing. The 24-disk x260 seems to have crapped out after about 800 rounds of load/unload due to the phys reporting devices, then no devices about 10s later, and then having the module unloaded before the dead SAS commands finished returning. Not sure what that's about, though I might also have borked the x260 :( Though who really is going to reboot the machine 800 times in rapid-fire succession??? (I'm not trying to slam the v28 sequencer, I'm merely providing a baseline for comparison between the two. It may very well be the case that all the bugs we used to observe with v17 were merely a result of us poking the sequencer the wrong way....) --D - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
