After adding a 40G ide disk(ad3) on my system, I 'ld like to devote some=20 extra space to FreeBSD (there is already a linux installation on the 40G=20 disk). However, after booting my -stable installation on the first=20 disk(ad0), I get the error message "excessive recursion in search for=20 slices" by the kernel on any attempt to access ad3 (mount a partition,=20 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=20 a userspace partition viewer (which understands the partition setup on ad= 3=20 when run under linux) I get simillar errors (ie infinite loop in the=20 partition handling code), which seem to stem from a read() returning sect= or=20 0 (the mbr of ad3) at somepoint in following the extended partition table= s=20 chain (do *not* consider this a fact, I could be wrong). I therefore conclude that this is not a problem in the partition handling= =20 code and given my lack of familiarity with the kernel I cannot even guess= =20 at the cause. For what it's worth, ->d_secperunit in the in kernel=20 disklabel is the same as the number of sectors reported by the linux=20 kernel. I can only assume that this is some obvious misconfiguration on m= y=20 part. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
