--- Comment #17 from Bill Sideris <bill...@feline.gr> ---
I got this bug too on arm, a Mekotronics R58X (RK3588 EDGE LP4x V1.0 BlueBerry
Board).

Stracing it, it gets stuck in reading /proc/cpuinfo, like how Sergio reported.

It goes like:
```
mprotect(0x7f9f2a1000, 4096, PROT_READ) = 0
write(3, "\1\0\0\0\0\0\0\0", 8)         = 8
openat(AT_FDCWD, "/proc/cpuinfo", O_RDONLY|O_CLOEXEC) = 7
statx(7, "", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT|AT_EMPTY_PATH, STATX_ALL,
{stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0,
stx_mode=S_IFREG|0444, stx_size=0, ...}) = 0
statx(7, "", AT_STATX_SYNC_AS_STAT|AT_NO_AUTOMOUNT|AT_EMPTY_PATH, STATX_ALL,
{stx_mask=STATX_BASIC_STATS|STATX_MNT_ID, stx_attributes=0,
stx_mode=S_IFREG|0444, stx_size=0, ...}) = 0
read(7, "processor\t: 0\nBogoMIPS\t: 48.00\nF"..., 16384) = 1923
read(7, "", 14461)                      = 0
read(7, "", 16384)                      = 0
read(7, "", 16384)                      = 0
```
And spams `read(7, "", 16384)                      = 0` forever.

```
