I need multiple LUNs on FC Fabric, and machine where these are on does boot from sata_sil mirror disks. During todays boots (after lengthy uptime), sata_sil driver was rather upset about some NULL pointer referrals. I had following extra boot line parameters: max_luns=4 max_report_luns=4 Taking off those two let kernel boot just fine. The kernels in question were Fedora Core development models from recent 2-3 weeks, including up to current date. /Matti Aarnio - : send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
