Re: [parisc-linux] kdb_v21 branch updated to -pa26, and kallsyms cross-compile

[joel.soete@freebel.net]

Hi all,

It seems that the b2000 I used to test gcc-3.2 does not crash anymore :) with
all kernels :)) (pl 2.4.18 or my stuff on 2.4.19)? (I feel that fs corruption
occurs and was not detected immideately?)

Well I come back to you to see what should be the useable kdb config (to
investigate the network problem with kernel compiled with gcc-3.1 or -3.2).

Mine is now:
CONFIG_MAGIC_SYSRQ=Y
CONFIG_KDB=Y
CONFIG_KDB_MODULES=Y
# CONFIG_KDB_OFF IS NOT SET
CONFIG_KALLSYMS=Y

Thanks a lot,
    Joel
