Maybe, maybe not. Building 6.11.11 with alpha-linux-gnu-gcc-9 (Debian 9.3.0-22) fixed the null pointer access in the scsi subsystem, and finally I have a bootable system! (Tested on ES45.) But I now get a null pointer access when network driver loaded: [ 34.501935] e100 0001:02:04.0 enP1p2s4: NIC Link is Up 100 Mbps Full Duplex [ 40.692361] Unable to handle kernel paging request at virtual address 0000000000000000 [ 40.799783] CPU 1 [ 40.799783] kworker/1:2(158): Oops -1 Cheers, Michael
