This is the unsuccessful result of an afternoon of bisecting: git bisect start # bad: [0ecfebd2b52404ae0c54a878c872bb93363ada36] Linux 5.2 git bisect bad 0ecfebd2b52404ae0c54a878c872bb93363ada36 # good: [e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd] Linux 5.1 git bisect good e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd # good: [e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd] Linux 5.1 git bisect good e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd # good: [a2d635decbfa9c1e4ae15cb05b68b2559f7f827c] Merge tag # 'drm-next-2019-05-09' of git://anongit.freedesktop.org/drm/drm git bisect good a2d635decbfa9c1e4ae15cb05b68b2559f7f827c # bad: [22c58fd70ca48a29505922b1563826593b08cc00] Merge tag 'armsoc-soc' # of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc git bisect bad 22c58fd70ca48a29505922b1563826593b08cc00 # bad: [c367dc8d0dd2a1e1ed9fdc2dd831053bdfdf0968] Merge branch # 'next-tomoyo2' of # git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security git bisect bad c367dc8d0dd2a1e1ed9fdc2dd831053bdfdf0968 # good: [45182e4e1f8ac04708ca7508c51d9103f07d81ab] Merge branch # 'i2c/for-5.2' of # git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux git bisect good 45182e4e1f8ac04708ca7508c51d9103f07d81ab # bad: [9b6c9e96f941c5ab13dad7278a3622f58e5672fc] Merge # git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc git bisect bad 9b6c9e96f941c5ab13dad7278a3622f58e5672fc # bad: [c1157f60d72e8b20efc670cef28883832f42406c] Merge branch # 'clk-parent-rewrite-1' into clk-next git bisect bad c1157f60d72e8b20efc670cef28883832f42406c Already c1157f60d72e8b20efc670cef28883832f42406c wouldn't boot, but one can see the error message "could not get tx clock" before both CPU cores get stalled. The next commit was f6111b9d7970df07f783d3891735003fef2bc37e, which also stalls on both CPU cores, but without emitting the "could not get tx clock" message. I don't know whether this kernel is good or bad. git log 45182e4e1f8ac04708ca7508c51d9103f07d81ab..c1157f60d72e8b20efc670cef28883832f42406c lets me end up with 189 lines of log A second unsuccessful result of bisecting just drivers/net/ethernet/stmicro/stmmac: git bisect start 'drivers/net/ethernet/stmicro/stmmac' # bad: [0ecfebd2b52404ae0c54a878c872bb93363ada36] Linux 5.2 git bisect bad 0ecfebd2b52404ae0c54a878c872bb93363ada36 # good: [e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd] Linux 5.1 git bisect good e93c9c99a629c61837d5a7fc2120cd2b6c70dbdd # bad: [f75b6f303bd80249a56cce9028954b4f731270e3] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net git bisect bad f75b6f303bd80249a56cce9028954b4f731270e3 # bad: [d4c26eb6e721683a0f93e346ce55bc8dc3cbb175] net: ethernet: stmmac: dwmac-sun8i: enable support of unicast filtering git bisect bad d4c26eb6e721683a0f93e346ce55bc8dc3cbb175 e9989339063dd3a566b67caaa857e6077bfee2cb ends up in a CPU soft lockup as well.
