freeBSD 4.9 stable hang on start_init: trying /sbin/init
After a power failure, my freebsd 4.9 stable is giving out the UDMA ICRC error. (see my first email below), but after a few boot, and change of a IDE cable, it is no longer giving out that error. However, it still hangs at boot at Mounting root from ufs:/dev/ads1a If I boot with boot -v option. It will stop at Start_init: trying /sbin/init This happens with my custom kernel and the default kernel. I also can't boot into single user mode using boot -s It is worth mentioning that I was able to boot the box from a FreeBSD 5.1 rescue CD, and remount all the partitions. I even used fsck and check all the partitions to make sure they are clean. But still can't boot from it. I have search the Internet, and it looks like quite a few people had the same problem during installation, but I didn't find any suitable solutions.

At first I was prompted to go into the single user mode, but then after second reboot that doesn't even happen anymore. Just the error message. I switch a IDE cable to the hard drive, and now, I don't even get the error message anymore. The system stuck at Mounting root from ufs:/dev/ad1s1a And it stuck there. I can reboot by ctr+alt+del I boot the system using the FreeBSD Fixit disk. However, I can't seem to see all the hard drive partitions in /dev. Following is my partition setup.

RE: freeBSD 4.9 stable hang on start_init: trying /sbin/init
Sergey, thanks for the answers. I did a # dd if=/dev/ad1s1a of=/dev/null bs=128k 2048+0 records in 2048+0 records out 268435456 bytes transferred in 7.044954 secs (38103223 bytes/sec) So it looks like my / partition in intact. I can mount and see all the file in that root partition as well as other ones. Just can get it to boot. I have tried resting my BIOs, no luck. I have tried to perform an upgrade from the 4.9 CD, but every time I get the point where it is looking for files on CD, it fails. I may try again from an FTP site. But I got the feeling reinstalling it will not fix the problem.

However, it still hangs at boot at Mounting root from ufs:/dev/ads1a If I boot with boot -v option. It will stop at Start_init: trying /sbin/init My bet is that the data in /sbin/init is broken. Do an md5 /sbin/init and send it to the list. Be sure to supply the date of your sources (as you're using STABLE, not 4.9-RELEASE) (or the output of ident /sbin/init). If nobody confirms the same checksum, then perhaps I'm right. This happens with my custom kernel and the default kernel.

I even used fsck and check all the partitions to make sure they are clean. But still can't boot from it. fsck will not necessarily notify you if there are hardware read errors somewhere on the drive. It just makes sure the filesystem areas are consistent and readable, not the data. If you use dd to read the whole disk, say # dd if=/dev/ad1s1a of=/dev/null bs=128k and it completes successfully, then it might be not a hardware fault, but something else. I'm sorry to say, but recently I had a power failure and it damaged my 80G Seagate (and FreeBSD gives pretty much the same errors when attempting to access the damages sectors). I have search the Internet, and it looks like quite a few people had the same problem during installation, but I didn't find any suitable solutions. -- DoubleF People will accept your ideas much more readily if you tell them that Benjamin Franklin said it first. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
