But FreeBSD 2.2.5 works properly, and on some other MBs w/ BM IDE interfaces (IWILL P55XB2, XXX with VIA 571) that kernel works too. Any maniplations with flags for wdc0 (0xa0ffa0ff -> 0), boot PROM HDD block modes/PIO modes/DMA modes settings, External/Internal caches didn't make anything good. After full initialization kernel just reports: Considering ffs rootfs, and system is freezes without any disk activity (HDD LED off any time after that). When break it to DDB we can see the following ps: proc addr flags stat wmesg wchan cmd 0xf0221cf0 0xf025c00 000204 3 biord f2735988 swapper ^^^^^ swapper goes in that state only from kern/vfs_bio.c:biowait() function after tsleep() with indefinite timeout. I think cause of its weird behaviour is some bugs/mistakes in PIIX BM IDE driver, or bugs in Intel TX chipset. >How-To-Repeat: boot:kernel -v >Fix: Unavailable. Thanks , Vasily .
