After adding a 40G ide disk(ad3) on my system, I 'ld like to devote some extra space to FreeBSD (there is already a linux installation on the 40G disk). However, after booting my -stable installation on the first disk(ad0), I get the error message "excessive recursion in search for slices" by the kernel on any attempt to access ad3 (mount a partition, fdisk -s /dev/ad3, or even a read() on ad3). Initially, I thought I had hit a bug in sys/kern/subr_diskmbr.c. Only, us= ing a userspace partition viewer (which understands the partition setup on ad= 3 when run under linux) I get simillar errors (ie infinite loop in the partition handling code). (it _seems_ that at somepoint in following the=20 extended partition tables chain, a read() returns sector 0 (the mbr of=20 ad3), but don't quote me on this) I therefore conclude that this is not a problem in the partition handling code and given my lack of familiarity with the kernel I cannot even guess at the cause. If it's any use, ->d_secperunit in the in-kernel disklabel is the same as the number of sectors reported by the linux kernel. Any ideas are _very_ welcome.
