Hello, on my Siemens Primergy 470 (dual PIII 450MHz) with two Symbios/LSI 83C895 I have great troubles: While booting FreeBSD it hangs on probing the SCSI devices. This error was in FreeBSD 5.3 STABLE 2, too! When will this bug being fixed? Here the SCSI tree and dmesg from FBSD 5.3: ------------------------------------------- primergy470# dmesg | grep sym sym0: <895> port 0x3000-0x30ff mem 0xf0200000-0xf0200fff,0xf0201000-0xf02010ff irq 23 at device 1.0 on pci2 sym0: Symbios NVRAM, ID 7, Fast-40, LVD, parity checking sym0: open drain IRQ line driver, using on-chip SRAM sym0: using LOAD/STORE-based firmware. sym1: <895> port 0x1800-0x18ff mem 0xf0101000-0xf0101fff,0xf0102000-0xf01020ff irq 17 at device 13.0 on pci0 sym1: Symbios NVRAM, ID 7, Fast-40, SE, parity checking sym1: open drain IRQ line driver, using on-chip SRAM sym1: using LOAD/STORE-based firmware.
