I try to update the Linux kernel to version 5.2.21.It can boot, lima driver seems working fine,but i can’t change sound volumn by launch, the screen stucked when I do this. Here is the dmesg output: > [0.000000] Booting Linux on physical CPU 0x0 > [0.000000] Linux version 5.2.21-clockworkpi-cpi3 (shell@shell-pc) (gcc version 7.2.1 20171011 (Linaro GCC 7.2-2017.11)) #1 SMP Mon Oct 14 09:39:13 CST 2019 > [0.000000] CPU: ARMv7 Processor [410fc075] revision 5 (ARMv7), cr=10c5387d > [0.000000] CPU: div instructions available: patching division code > [0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache > [0.000000] OF: fdt: Machine model: Clockwork CPI3 > [0.000000] Memory policy: Data cache writealloc > [0.000000] cma: Reserved 64 MiB at 0x6c000000 > [0.000000] On node 0 totalpages: 262069 > [0.000000] Normal zone: 1536 pages used for memmap > [0.000000] Normal zone: 0 pages reserved > [0.000000] Normal zone: 196608 pages, LIFO batch:63 > [0.000000] HighMem zone: 65461 pages, LIFO batch:15 > [0.000000] psci: probing for conduit method from DT. > [0.000000] psci: Using PSCI v0.1 Function IDs from DT > [0.000000] percpu: Embedded 15 pages/cpu s30476 r8192 d22772 u61440 > [0.000000] pcpu-alloc: s30476 r8192 d22772 u61440 alloc=15\*4096 > [0.000000] pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 > [0.000000] Built 1 zonelists, mobility grouping on.
