Pavan,
Thanks for assistance.
The Grub entry 'root (hd0,2) was indeed working before my upgrade to 137.
When I specify 'root (hd0,1)', even with chainloader +1, I get 'Invalid
system disk' error (something similar)
The last 10 characters of /dev/sda2 are not '*SWAP*'

Any thing else to try? Thanks.

Pavan,
Here is the fdisk -l output. OpenSolaris partition is the active
partition.
hmmm...
Then, your grub entry should really be:
------------------
root (hd0,1)
chainloader +1
boot
------------------
and not:
root (hd0,2)
I think GRUB starts counting the partitions from 0.
If even this does not resolve the matter, check if the solaris partition
has been used as SWAP by Linux.
Try:
dd if=/dev/sda2 bs=4096 count=1 | od -c
and see if the last 10 characters in the output of "od -c" is SWAP_SPACE
or SWAPSPACE2

I have been switching between OpenSolaris and Ubuntu (Lucid Lynx).
I had installed OpenSolaris first and then Ubuntu. So, Ubuntu's
Grub2 became my boot manager.
It was working fine, till I did a upgrade to OpenSolaris build 137
(internal bits). A reboot from OpenSolaris worked. But, after a hard
reboot, with GRUB2 failed.
After choosing 'OpenSolaris' from my Grub menu ("root (hd0,2);
chainloader +1; boot), all I see now is the blinking cursor instead
of OpenSolaris' grub.
Any help on how to get back to OpenSolaris (I am stuck with Ubuntu
now). Thanks.
When it was working, what build of OpenSolaris were you using?
Try making the partition on which OpenSolaris resides as the active
partition, and see if things work.
A partition map - output of "fdisk -l" from the linux installation
will help understand the problem better.
