DragonFlyBSD

Hi all,



i'm running v2.11.0.397.g4b06a0-DEVELOPMENT x86_64



I got this kind of panic on a daily basis, always at night (probably

while hammer does reblocking?):



Jun 20 03:09:14 randy kernel: ahci0.1: disk_rw: unknown state 6

Jun 20 03:09:14 randy last message repeated 18 times

Jun 20 03:09:14 randy kernel: panic: Bad link elm 0xffffffe01e019e78

next->prev != elm

Jun 20 03:09:14 randy kernel: boot() called on cpu#0



After applying these two patches it's running stable since 4 days.



The difference is now that TAILQ_EMPTY (patch 0002) is in

camisr_runqueue() *and* is protected by a spinlock too. The last maybe

fixes the panic? Does it makes sense?



ByE!
