Hi, I'm using the latest (ok, 17th November, 10am pacific time) git tree on the Broadcom BCM91250 that I've always had problems with/nightmares about. I'm getting a data bus error and am wondering if there are any un-gitted patches circulating that fix the problem and/or can diagnose better what is going on. After turning on ALL of the debugging Linux has to offer (and then some), this is the part of the boot log that shows what is happening: [42949373.640000] Good, all 218 testcases passed! | [42949373.650000] --------------------------------- [42949373.650000] Dentry cache hash table entries: 32768 (order: 6, 262144 bytes) [42949373.660000] Inode-cache hash table entries: 16384 (order: 5, 131072 bytes) [42949373.700000] Memory: 247296k/260764k available (3030k kernel code, 13152k reserved, 1123k data, 232k init, 0k highmem) [42949373.960000] Mount-cache hash table entries: 256 [42949373.970000] Checking for 'wait' instruction... unavailable.
