>Description:
Quantum LPS540S doesn't implement cache flushes.
>How-To-Repeat:
Simply shutting down the system will expose the error short
before the expected "System is halted" message.
>Fix:
A quirk in scsi_da.c is in order. Adding something like this
will do:
{ {T_DIRECT, SIP_MEDIA_FIXED, quantum, "LPS540S", "*"},
DA_Q_NO_SYNC_CACHE },
BTW, I suspect all the LPS line from Quantum suffers of the
same problem. If this is confirmed, simply changing the
already existing quirk for the LPS525S (lines 201-207) will do:
{
/*
* Doesn't like the synchronize cache command.
*/
{T_DIRECT, SIP_MEDIA_FIXED, quantum, "LPS*", "*"},
/*quirks*/ DA_Q_NO_SYNC_CACHE
},
Note the more general matcher for the product name.
