Device: HP EliteBook 745 G6
CPU: AMD Ryzen 5 PRO 3500U
OS: Xubuntu, Kernel 6.17.0-19 and 6.17.0-20 (both affected)
Antigravity version: 1.22.2
Language server crashes immediately with CRNGT failed / SIGABRT.
Kernel disables RDRAND on this platform at boot: “RDRAND is not reliable on this platform; disabling.”
The language server binary uses BoringCrypto FIPS which hard-requires RDRAND. When the kernel disables it, the CRNGT self-test aborts before sending start data. This worked on a previous Antigravity version — a recent update introduced this BoringCrypto FIPS requirement.
