I've installed 4.1-RELEASE few days ago and it worked well with GENERIC kernel provided with release. Thereafter I found that SoundBlaster Live! value made noise when mp3 played. So i cvsuped to 4.1.1-STABLE and sound bug fixed. However, ahc driver doesn't work correctly. After cold boot, ahc driver complains as follows while booting: ---------- ahc0: port 0xa400-0xa4ff mem 0xe1800000-0xe1800fff irq 5 at device 10.0 on pci0 aic7870: Single Channel A, SCSI Id=7, 16/255 SCBs . . . ppi0: on ppbus0 panic: ahc0: brkadrint, Scratch or SCB Memory Parity Error at seqaddr = 0x0 ---------- Reboot after 15 seconds. After warm boot, boot process is ok. What's going on? In addition, I tried to insert AHC_ALLOW_MEMIO into config file and turn off Parity Checking in SCSI BIOS. All these couldn't help me. Panic source is in /usr/src/sys/dev/aic7xxx/aic7xxx.c -> ahc_handle_brkadrint() -> panic("%s: brkadrint, %s at seqaddr = 0x%x\n", ...) System spec.: Athlon 800Mhz with ASUS A7V, 128MB and etc. Adaptec 2940 SCSI adapter SoundBlaster Live! value Does any one help me? Thanks in advance.
