kernel 4.15.0-22-generic system hangs duting boot

[Sudhakar Dayal]

I have ideapad S10-3. I am booting Ubuntu 18.04 from 32 Gb SanDisk USB 2. During the normal boot process the ststem refuses to boot further. During the boot process, first five dots go well. After the SIXTH dot appears, the cursor also appears in GUI mode .... beyond that, the system hangs forever.

Even during recovery mode, the text appears up to

[OK] Reached target sound card ...

beyond that the system hangs, but if ^C is typed from the key board, the boot process continues and and the normal GUI interface is established

:-)
