Hello,
I get an easy to reproduce panic on recent RELENG_6/amd64 :
-su-2.05b# /compat/linux/bin/bash
bash-2.05b# cd /dev
bash-2.05b# ls
panic : kmem_malloc: entry not found or misaligned
Setup is as follows :
/dev/ad0s3d mounted on /
/dev/ad0s4d mount on /files
/usr is a symlink to /files/amd64/usr if ever that might be of
importance (the rest of ad0s3 is RELENG_5/i386)
uname -a :
FreeBSD demo 6.0-RC1 FreeBSD 6.0-RC1 #1: Sat Oct 29 17:04:50 CEST 2005
toor@demo:/files/amd64/obj/files/bsd/src6/sys/D470K amd64
generic config-file with outcommented non-needed drivers and extra options :
device cpufreq
device tap
device atapicam
device sound
device smbus
device iicbus
device iicsmb
options NTFS
options TCP_DROP_SYNFIN
linux_base-8-8.0_7 installed.
NB, please respond preferentially to list; i still need
a good solution to filter important email from my flooding
"misc" procmail-filter output ;(
