Hello, I have a Fujitsu Siemens TX200 S2 (2x Xeon on board) with a LSI MegaRAID 320-0X. I configured a RAID 5 disk array - but the problem dont go away if I configure no raid (only physical drives). If I boot GENERIC with "apic" enabled in the kernel the amr driver responses amr0: adapter is busy three times, then the system hangs. If I disable "apic" the system boots as expected, the logical drive could be used for installation. The amr driver prints two lines about the size of the logical drive instead. I installed the system in "safe mode", everything works as expected. But if I enable "apic", the "busy" comes up. I tried building a new SMP kernel, same as above: using a "one line" empty loader.conf with disabled apic makes the system running. I tried some combinations of acpi, apic, ata-dma, .... (the system only has a ata cdrom). No chance, only disabled apic get it up. I tried FreeBSD 5.4-stable. I also downloaded a (unsupported) driver from LSI webserver, this prints the size of the logical array, but hangs too. I then compared the native 5.4 driver with the -current, only one cosmetic changes. So I expect testing -CURRENT has no effect ? Is it worth to spend time on this? Is it a bug?
