Hello, Some weeks ago, I have indicated here I have a stability issue with my Blade2000 running NetBSD : trap type 0x68: cpu 1, pc=410657c0 npc=410657ac pstate=0xffffffff99820092<,PEF,IE> Skipping crash dump on recursive panic panic: +fast data access MMU miss cpu1: Begin traceback... cpu1: End traceback... cpu0: shutting down cpu1: rebooting That was with 6.99.40 kernel. I have changed a faulty memory module, rebuilt all packages I use from sources (perl, gtk and all dependencies) and rebuilt a new kernel : NetBSD legendre.systella.fr 6.99.47 NetBSD 6.99.47 (CUSTOM) #1: Sun Jul 20 15:21:37 CEST 2014 [email protected]:/usr/src/sys/arch/sparc64/compile/CUSTOM sparc64 CUSTOM stands for GENERIC.MP with some minor modifications : sd0 at scsibus4 target 0 lun 0 sd1 at scsibus4 target 1 lun 0 cd0 at scsibus0 target 6 lun 0 ... # Wedge support options DKWEDGE_AUTODISCOVER options DKWEDGE_METHOD_GPT With 6.99.40 kernel, this workstation was stable enough to build packages from sources (load average : 6). With 6.99.47, it has hanged just after a few hours. At 12:48 (CEST), this workstation has crashed under heavy I/O (gcc48 compilation). Something very similar to a deadlock and I have rebooted it with power button. Console didn't respond, network subsystem didn't answer to ping... There was no information on console or serial line. No panic and no dump file. I don't think if it is sparc specific, I don't have any other information. Has anyone ever seen the same problem? Best regards, JB
