range of 32 bit unsigned int/long
dear all, i am a bit confused over this. the 16 bit unsigned integer takes the value as i checked myself for 0 to 2^16-1 (=65535). but the 32 bit unsigned integer/long does not take the value from 0 to 2^32-1 (4294967295). instead 32 bit unsigned int/long takes the value from 0 to 2^31-1 (2147483647). the gcc shows that the message warning: this decimal constant is unsigned only in ISO C90 what is happening, i am confused. kamal. __ Do You Yahoo!?

kernel crash dump could not be obtained
dear all, i have to make modifictions to the kernel and i have been encountering kernel crashes all the time. the kernel panics with messages starting with vm_fault: and then crashes and reboots. i guess i have done incorrect memory operations and i want to know where i went wrong. so i thought of obtaining the crash dump. i went through the developers guide. and i added the following lines on the /etc/rc.conf --- dumpdev="/dev/ad0s1b" dumpdir="/var/crash" savecore_flags="" -- the /etc/fstab file is Device Mountpoint FStype Options DumpPass# /dev/ad0s1b noneswapsw 0 0 /dev/ad0s1a / ufs rw 1 1 /dev/ad0s1e /tmpufs rw 2 2 /dev/ad0s1f /usrufs rw 2 2 /dev/ad0s1d /varufs rw 2 2 /dev/acd0 /cdrom cd9660 ro,noauto 0 0 swap partition is /dev/ad0s1b swapinfo gives the output:-- Device 1K-blocks UsedAvail Capacity /dev/ad0s1b4950480 495048 0% My memory size according to dmesg is -- real memory = 266600448 (254 MB) avail memory = 251232256 (239 MB) -- Now when the kernel crashes it prints the message writing dump 240MB but rebooting does not show any crash dump file on /var/crash. please help kamal __ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
