Hi,
the next mail has a patch to offline a device when eh is activated
again and again.
Presently I have a system stopping to boot because one of the scsi-devices
is in something like a zombie state.
Without the patch, the eh is called in an endless loop, with the patch,
it now deactivates the device, but still doesn't proceed to boot. Probably
since the last scsi command never returns?
