I have a slight problem, I swapped by CD Writer (HP 8100) with a CD-Reader (Mitsumi) and rebooted. I get a new error during the boot process... immediatly following: | acd0: CD-RW <...> | Mouning from root iso9660:cd0a | no such device 'cd' | setrootbyname failed | iso_mountroot: can't find rootvp | Root mount failed: 6 | Mounting root from iso9660:acd0 acd0: READ_BIG - MEDIUM ERROR asc=02 ascq=0 error=00 Root mount failed: 5 no such device 'wcd' set rootbyname failed cd9960: Rockridge Extension acd0: READ_BIG - command timeout - resetting bus error ... bunch more READ_BIG MEDIUM ERRORs and timeouts then a "vm fault pager read error", then a "bus error core dumped"... then it ends saying that it can't mount fstab so startup is aborted. ... Does this have anything to do with the following error? | During burning the iso image, I get a message to my | console, PREVENT_ALLOW - ILLEGAL REQUEST asc=64 ascq=0 error=04 | this occurs as burncd is "fixing". I replaced the reader with the writer and all is well, so, I see a few potentials for this problem: (a) bad media (b) bad writer (c) bad reader (d) imperfect software (e) some combination It's about time I replaced by CD-Writer and got a new CD-Reader, any brands that you recommend? I can get new media while I'm at it. By the way, another group of warnings appear in both boot cases... Warning: Bytes per inode restrict cylinders per group to 9 Warning: Inode blocks/cylinder group (285) >= data blocks (256) in the last cylinder group, this implies that 4096 cylinders cannot be allocated 496 blocks Warning: Block size restricts cylinders per group to 26 496 blocks mounting non-volitle disk Is this something to be worried about? Thank you all so much. Best, Clark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
