Booting with "profile=sleep,2" is broken in 2.6.23-rc9 and 2.6.23-rc8 but working in 2.6.22. I was checking it out as part of a discussion in another thread and noticed it broken in -mm as well (2.6.23-rc8-mm2). Bisect is in progress but suggestions as to the prime candidates are welcome or preferably, pointing out that I'm an idiot because I missed twiddling some config change. 2.6.22 output gringo:~# readprofile | sort -rn 69604 total 0.0309 27287 m_start 243.6339 16430 sync_page 205.3750 13161 sync_buffer 205.6406 4035 sys_init_module 0.6121 2842 msleep 88.8125 2573 call_usermodehelper_keys 10.7208 1554 ps2_sendbyte 6.0703 803 log_wait_commit 2.7882 378 do_lookup 0.9844 160 do_get_write_access 0.1111 89 synchronize_rcu 1.3906 76 ps2_command 0.0792 66 ide_do_drive_cmd 0.2292 59 do_fork 0.1085 54 congestion_wait 0.3750 29 __rtnl_unlock 1.8125 4 kthread 0.0357 2 *unknown* 2 journal_stop 0.0038 1 kthreadd 0.0035 1 kthread_create 0.0063 latest git output gringo:~# readprofile 0 *unknown* 0 total 0.0000 I checked the obvious stuff like DEBUG options being set, CONFIG_PROFILING being set etc. > So there's a final -rc out there, and right now my plan is to make this > series really short, and release 2.6.23 in a few days.
