The issue seems to be the invocation of block layer API (generic_make_request) from the softirq context which is actually the callback of another IO or a XOR operation. Apparently, the callbacks are being invoked in timer context, as it's seen from the call stack, which is an interrupt and we cannot sleep in interrupt context, hence the bug. xprtsock.c source code [linux/net/sunrpc/xprtsock.c ... static unsigned int min_slot_table_size = RPC_MIN_SLOT_TABLE; 86: static unsigned int max_slot_table_size = RPC_MAX_SLOT_TABLE; 87: static unsigned int max_tcp_slot_table_limit = RPC_MAX_SLOT_TABLE_LIMIT; 88: static unsigned int xprt_min_resvport_limit = RPC_MIN_RESVPORT; 89: static unsigned int xprt_max_resvport_limit = RPC_MAX_RESVPORT; 90: 91 SuperH Interfaces Guide - kernelnewbies.org that was previously inserted into the kernel page table and discards the UTLB translation. 1.2.

To mitigate this issue, add an AMD handle_irq callback function, amd_pmu_handle_irq(), that will invoke the common x86_pmu_handle_irq() function and upon return perform some additional processing that will indicate if the NMI has been handled or would have been handled had an earlier NMI not handled the overflowed PMC.
