See issue 2037, possible fix committed. It looks like there may have been a
race in tsleep() where the stack-declared callout structure could wind up not
being reset prior to tsleep() returning.

Hi Matt,

unfortunately still not ok (for me). Two panics in the last 24 hours (strangely no core dumps) on x86_64.

This issue is in my case unrelated to package building, it happended at times when i wasn't working on the machine, i.e. it was supposed to be (almost) idle.

  • with v2.9.1.1706.gc368d-DEVELOPMENT

Apr 20 14:56:52 randy syslogd: kernel boot file is /boot/kernel/kernel
Apr 20 14:56:52 randy kernel: spin_lock: 0xffffffe005dab660, indefinite wait!
Apr 20 14:56:52 randy kernel: panic: Bad link elm 0xffffffe042c67878 next->prev != elm
Apr 20 14:56:52 randy kernel: cpuid = 0
Apr 20 14:56:52 randy kernel: boot() called on cpu#0
Apr 20 14:56:52 randy kernel: Uptime: 2h51m44s
....
and so on with same pattern many times; rest of output is corrupted and unreadable

and this after update to v2.11.0.4.ge92d7-DEVELOPMENT:

Apr 21 03:08:49 randy syslogd: kernel boot file is /boot/kernel/kernel
