According to John-Mark Gurney: > >From the ATA spec: > If there is data in the write cache, that data shall be written to the > media.

Default for all commands except FLUSHCACHE seems to be 5s with 2 retries. FLUSHCACHE is timeout is 1s w/o retries at all in ata-disk.c. As I said, allowing one retry makes it running longer it still panics. It panics inside UMA only if the FLUSHCACHE timeout occurs on both disks at the same time, I've not been able to track it back and I don't have my Macintel today with me. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto_at_keltia.freenix.fr Darwin sidhe.keltia.net Kernel Version 8.8.2: Thu Sep 28 20:43:26 PDT 2006 i386Received on Wed Apr 25 2007 - 07:11:28 UTC
