Hi all,
I'm a bit new to RAID so I hope I'm not making a dumb mistake, but
here goes..
System: Dell PowerEdge 2300/450 (PII-450x2, 512MB RAM)
SCSI: AIC-7890, AIC-7860
All filesystems are on RAID (/, /usr, etc.), necessitating boot via
'initrd' method. (I *think* this is hardware RAID, since there's no
sign of the /dev/md0 device being used; as I said, i'm new to this.)
The 2.2.12-20 kernel (both uni and smp versions) boots fine, using the
megaraid 1.04 (dated August 16, 1999) driver.
The 2.2.16-3 kernel crashes though, when megaraid tries to mount the
RAID root. (the version in 2.2.16-3 is v1b08b, dated June 13, 2000)
Here's an excerpt from the boot up showing the crash.
megaraid: v1b08b (June 13, 2000)
