According to Daniel O'Connor: > I see this when using gjournal too. Good so it is not zfs-specific. > I suspect the timeout on the flush cache command needs to be increased. > I haven't got around to testing it but you could try increasing the > timeout in ata-disk.c (around line 280) -> The main problem that I've found is that with a single disk configuration, there is a timeout then the system recovers but with a dual (or maybe more) disks involved, multiple/current timeouts make the system panic and that is not nice. I suspect that changing the timeout may just hide the real problem. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr Darwin sidhe.keltia.net Kernel Version 8.8.2: Thu Sep 28 20:43:26 PDT 2006 i386
