Hi All,
We have a kernel module called IPFS which lies in between VFS and UFS. We are getting a kernel panic (with the following stack trace) very frequently on ATCA blades where as the panic is almost rare on CPCI blades. sfmmu_tsbmiss_exception+0x54(2a1038555a0, 42001, 31, 0, d5b28, 6001e6d0800) ktl0+0x64(60008a47564, 42f98, 1, fffffffffffffff8, 1e5b76, 1) uiomove+0x90(60008a4755c, 8, 0, 2a103855950, 0, 8) struiocopyout+0x38(60008cf2fc0, 2a103855950, 2a103855864, 0, 60008a47564, 1) strread+0x4b4(0, 2a103855950, 0, 6001f93fd28, 0, 0) ipfs_in+0x1e8(0, 30022006540, 6001f93fd28, 8, 2a103855ab0, 0) ipfs_active_in+0xec(60005e8c000, 30022006540, 3001f1f5ec0, 60011bc6000, 0, 60005e8c0d8) thread_start+4(60005e8c000, 0, 0, 0, 0, 0). When can this sfmmu_tsbmiss_exception occur? Thanks in advance Regards, Priya
