--3Gf/FFewwPeBMqCJ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I just had a crash, luckily I could dump a core with 'call doadump'. However something with the serial console was wrong so my screen was spammed with %%% (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort)= (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort= ) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abor= t) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abo= rt) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to ab= ort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to a= bort) (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) %%% etc. Now I did not worry about this because I thought I could use kgdb on the dump after the reboot. However it seems that kgdb is running into some infinite loop printing these messages; I have ran it for about 20 minutes where it kept repeating this message, with some block nrs. intertwined. I think it repeats though because I have seen block nr '96' (lucky ^S timing) and it still doesn't stop. Is there a way to *not* print the 'Unread portion of the kernel message buffer' (as it is apparently called) on startup? --Stijn --=20 Coffee is the path to the bouncy side. Coffee leads to activity. Activity leads to moving. Moving leads to bouncing. =2E.. (meaningful silence) ... I sense much coffee in you. -- Matthijs Piek --3Gf/FFewwPeBMqCJ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQFDvnnGY3r/tLQmfWcRAktyAJ44sNid2NOY3SaYXxQ2+xYrdRG+bgCbBQAa 0BmkVZW8RK+mlJzXukHtSLc= =q2ie -----END PGP SIGNATURE----- --3Gf/FFewwPeBMqCJ--
