>Description:
I hope I made not very bad BugReport - I do it for the first time.
I have AcerAltos 9000M9B with Mylex 960PL RAID 0 (8 HDDs - QUANTUM FIREBALL-TM3200S 3067MB).
I've installed FreeBSD 4.1-RELEASE on fixed HDD - da0 at ahc0 (aic7880).
First of all I made /pub filesystem from /stand/sysinstall.
Test#0: cp /etc/passwd /pub - OK.
Test#1: cp /etc/* /pub - failed.
/var/log/messages(and console):
/kernel: bus_dmamap_load: Too many segs! buf_len = 0x10000
/kernel: mlx0: I/O error - attempt to write beyond end of drive
Than I try to make it by hand (fdisk, disklabel, newfs, mount) and receive the same result.
Than I try to make 10Mb disk and receive the same result.
Than I download last mlx driver sources from CVS and receive the same result.
Now I can't resolve this problem.
There is some system params - if you want:
mylex configurator report,
fdisk /dev/mlxd0 report,
disklabel /dev/mlxd0s1 report,
/var/log/messages.
