Hi, Is there a way to reproduce this? Cheers, Antonio Huete ---------------------------------------- Bug #1218: panic: assertion: error == 0 in hammer_start_transaction http://bugs.dragonflybsd.org/issues/1218#change-12512 * Author: rumcic * Status: In Progress * Priority: Normal * Assignee: * Category: VFS subsystem * Target version: 4.2.x ---------------------------------------- The machine was mostly idle and the panic happened during the night when I was sleeping, so I don't remember much what I was running. The only thing I do remember, was a vkernel running under gdb (still have to find out why when running a diskless vkernel outside gdb it displays quite a few "RPC timeout for server 192.168.0.16" before the network starts working and goes on booting, but if I run the vkernel under gdb, I only get perhaps 2 of those messages and after that nothing happens - gets stuck) which was semi-diskless (root on nfs, and one hammer fs partition on the first vkd, but since it was stuck at the RPC timeout messages it shouldn't have gotten far enough to mount the root, let alone the local hammer partition - unless it started booting sometime during the night). The backtrace: panic: assertion: error == 0 in hammer_start_transaction mp_lock = 00000000; cpuid = 0 Trace beginning at frame 0xe28c9968 panic(e28c998c,c02c6806,e28c9a84,c39a6738,e28c99a8) at panic+0x14d panic(c03d0698,c03de4df,c03bbd41,6,45d61) at panic+0x14d hammer_start_transaction(e28c9a84,debc0000,c39a6738,1,1) at hammer_start_transaction+0x41 hammer_ioctl(de0bc550,c02c6806,e28c9c1c,1,c39a6738) at hammer_ioctl+0x2d hammer_vop_ioctl(e28c9ae0,c04314e0,d272ad10,e27c46e8,0) at hammer_vop_ioctl+0x2f vop_ioctl(d272ad10,e27c46e8,c02c6806,e28c9c1c,1) at vop_ioctl+0x38 vn_ioctl(d61e90c0,c02c6806,e28c9c1c,c39a6738,d61e90c0) at vn_ioctl+0xbf mapped_ioctl(4,c02c6806,bfbff8e0,0,e28c9d34) at mapped_ioctl+0x3e1 sys_ioctl(e28c9cf0,6,1e82,0,d8f675d8) at sys_ioctl+0x16 syscall2(e28c9d40) at syscall2+0x265 Xint0x80_syscall() at Xint0x80_syscall+0x36 boot() called on cpu#0 The dump is located at leaf:~rumko/crash/{kernel,vmcore}.0 The kernel was compiled on the 2nd January around noon CET ... so the sources should have been from around then as well. -- Regards, Rumko -- You have received this notification because you have either subscribed to it, or are involved in it.
