This tests that an uncompressed kernel image is available. This is included in debug packages (linux-image-<version>-<flavour>-dbg). However, due to size constraints, at most only one flavour per architecture has such a debug package, and for i386 this is the '686-bigmem' flavour. You can use this script to decompress the vmlinuz file, but that won't include debug information so I'm not sure how useful it is to perf: svn://svn.debian.org/kernel/people/benh/zcat-linux-image > 2: detect open syscall event: FAILED! > > 3: detect open syscall event on all cpus: FAILED! The test is wrong. Syscall events are optional and we haven't enabled them. > johan@johansdator:~$ > " > > I don't know how much this matters in practice. Probably not much; perf seems to work. Maybe we ought to patch the test though... Ben. -- Ben Hutchings Once a job is fouled up, anything done to improve it makes it worse.
