I've found a problem with CentOS 3 latest kernel (2.4.21-27.0.1.ELsmp)
and megaraid2 driver.
Hardware: Dell PE1600SC with CERC ATA100 RAID controller
The problem is somewhat similar, but not identical as:
After updating new glibc and kernel packages the new kernel don't boot.
Boot fails to mount root fs with "Cannot open root device" message.
I doublechecked that /etc/modules.conf is refering to megaraid2 as it
should and then recreated initrd manually, no help. Older kernel version
(2.4.21-20.0.1.ELsmp) boots just fine.
As RHEL3 U4 release notes states:
The megaraid2 driver has been updated from v2.10.6 to 22.214.171.124-RH1
The new driver is scsi/megaraid2.o
The older driver has been preserved as addon/megaraid_2106/megaraid_2106.o
So I decided to try megaraid_2106, changed modules.conf, recreated
initrd and... server booted with the new kernel!
Could there be a problem with the latest megaraid2 driver
(126.96.36.199-RH1)? Since I'm using CentOS and not RHEL, how/where I could
report this problem?
