Boot off the ide disk and fsck the scsi disks.

They have stock Mandrake 7.2 (kernel 2.2.17-21mdk) and have installed serial-5.05 into it. The kernel boots to the Freeing message and hangs. I noticed ctl-alt-del still works, so I configured in magic sysrq (Documentation/sysrq.txt). sysrq-p allowed me to get the eip, which checking against the System.map I find is mod_timer(). A quick printk showed me that the kernel isn't hung, it's in an infinite loop, with mod_timer() being one of the calls in the loop. YMMV, but hopefully this method can help you find your problem. ..Stu - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

These happen frequently to me (when compiling and installing a new glibc) But in this case you would have other messages (IIRC something like respawn too fast). Thus the problem is not this! Possible problem: 1) permition of /sbin/init 2) unable to exec ELF binary (or a.out, which init do you have?) 3) problems with the root partition. (check it with an emergency disk) 4) once I had strange problem with init and /dev (init was continuosly killed, but after some init.d scripts).

Re: URGENT : System hands on "Freeing unused kernel memory: "
I have 2 ideas: * glibc corrupted * did you downgrade the cpu? RH 7.0 automatically installs glibc for a Pentium Pro or later if that cpu is present during install. If you then move the hd into a computer with an AMD K6, it won't boot. I'd run #rpm -Va and check if some unusual files are modified (...5.. without "c") -- Manfred - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
RE: URGENT : System hands on "Freeing unused kernel memory: "
Does it hang forever ? I've noticed that my kernel (2.4.2) stalls for several minutes with the same message but suddenly after that the login prompt appears (anything between, like configurations and services starting messages, are gone). We've been able to track it down to a change we did to /etc/lilo.conf to add support for kernel prints to go out to a serial debugger. Before that everything was OK, but after we added append="console=tty0 console=ttyS1,38400", this problem started. We did notice however that everything that doesn't appear on the console does appear on the serial debugger.
