Hi, This was one occurrence only and lately on LSPCON issues (dmesg warnings) that are now gone by BIOS update.

It is too early to close this. It is probably a duplicate of BUG 103022, but since we have no information in this incomplete how can we know.

This should remain open until we have valid statistical reasons to close it.

OK, lets follow on cibuglog but dropping priority.
