The problem occurs whenever the output from the boot phase is garbled, almost always because this output: SMP: AP CPU #1 Launched! messes up this output (or similar): cd0: cd present [2222160 x 2048 byte records] The symptom is that _all_ userland output disappears, which makes it rather difficult to do anything. I'm forced to reboot the box until the boot output isn't trashed. If I break into ddb then all the output becomes visible, but leaving ddb then results in no userland output appearing again. I noticed this problem for the very first time after gcc42 was imported. In all the years I've been using FreeBSD (since 1993) I've never seen any behavior like this before. This leads me to strongly suspect some fallout from gcc42. Has anyone else seen this? --- Gary Jennejohn / garyjATjennejohnDOTorg gjATfreebsdDOTorg garyjATdenxDOTde
