Re: Qemu crash...
FIne. Are there any links to howtos explaining how to go about the pertinent forensics? Much of the literature on strace and the kernel debugger seem to be documented by persons suffering from asperger syndrome. Basically I load the module and the emulated winXP croaks when the logo starts fading in. I unload and everything is 'ok'. By 'OK' I mean brutally slow only, but no crashing. O6 makes things a little faster. Regardless, it doesn't affect this issue.

Re: Qemu crash...
You need to include AIO support in your kernel (or as a module). The port should be updated to mention this. As has already been said this is mentioned in the pkg-message, ppl just dont seem to look there... (I just answered the second pr about this too :) Is there a better place? *Doh* ;-) I'll try this on monday... :-) Thanks, -- Best regards / Viele Grüße, [EMAIL PROTECTED] Simon Barner[EMAIL PROTECTED] pgp0oKCqbTc3o.pgp Description: PGP signature
Re: Qemu crash...
I haven't been able to get qemu to work at all with the kqemu kernel module. I notice that the build in the 6.2 prerelease doesn't appear to bother using the kqemu module. Perhaps that is the origin of it's stability. Anyway now I have an emulated widows that crawls compared to earlier qemu versions and no idea when it will be running the way it did a year ago. On the bright side, qemu compiles nicely with O6, though I had to kill a comma in my CFLAGS to get sed uncroaked on the build.

I thought the following would do the trick: kldstat -m aio /devnull 21 || kldload aio Ugh I forgot about the -q switch. kldstat -qm aio || kldload aio ___ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to [EMAIL PROTECTED]

What I suggested works for qemu since kldstat -m works for aio and kqemu. May be people tried kldload without checking if the module existed? kldload should do the equiv. of kldstat -m. The conditions of the panic are that a user has a module already compiled in statically to their kernel, and mistakenly tries to kldload a second copy of it. Beyond this I do not remember details other than that it is still being reported from time to time. There's still the stale module problem. You mean an old module that you want to replace? No, a module compiled for a different kernel version (e.g. the user ran cvsup and rebuilt modules but has not yet built or booted the new kernel). Modules are notoriously fragile things, even in -stable. No, it only works for things that are modules: grep -i compat /usr/src/sys/i386/conf/XOR options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_LINUX Ah, I see what you mean... The quick way is to default to options INCLUDE_CONFIG_FILE but the DEFAULTS file has muddied the situation as its contents are not shown. May be it is better for config(8) to generate necessary sysctl glue for options, makeoptions etc. Even better if sysctl kern.config can used to recreate the config file of a running system That's more or less what I was suggesting. There should be a one stop shop for user programs to figure out the full set of running kernel features. Kris pgpYznj6VmI88.pgp Description: PGP signature
