Package: src:linux Version: 5.19.11-1 Severity: important Dear Maintainer,
I have a XEN hypervisor running with some VMs (everything based on Debian). After updating to the Kernel to 5.19 (from 5.18.0-4), some binaries are falling to execute. If the VMs are started with Kernel 5.18.0-4 they are running fine. One example is wget which results in this kernel log: [ 366.744374] traps: wget[3327] trap invalid opcode ip:7fcabc94fb0a sp:7fffdd212c80 error:0 in libgnutls.so.30.34.1[7fcabc837000+12f000] After googling a little I found this stackoverflow problem report: https://stackoverflow.com/questions/65676095/illegal-instruction-core-dumped-after-packages-upgrade-on-centos-8 And indeed there is some difference in /proc/cpuinfo: 5.19: flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush mmx fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc rep_good nopl cpuid tsc_known_freq pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 movbe popcnt aes f16c rdrand hypervisor lahf_lm abm 3dnowprefetch cpuid_fault ssbd ibrs ibpb stibp fsgsbase bmi1 bmi2 erms rdseed adx clflushopt md_clear 5.18: flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush mmx fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc rep_good nopl cpuid tsc_known_freq pni pclmulqdq ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand hypervisor lahf_lm abm 3dnowprefetch cpuid_fault ssbd ibrs ibpb stibp fsgsbase bmi1 avx2 bmi2 erms rdseed adx clflushopt xsaveopt xsavec xgetbv1 md_clear So the flags for "fma xsave avx2 bmi2 xsaveopt xsavec xgetbv1 md_clear" are missing, which might result in gnutls failures. regards Patrick -- Package-specific info: ** Version: Linux version 5.19.0-2-amd64 (debian-ker...@lists.debian.org) (gcc-11 (Debian 11.3.0-6) 11.3.0, GNU ld (GNU Binutils for Debian) 2.38.90.20220713) #1 SMP PREEMPT_DYNAMIC Debian 5.19.11-1 (2022-09-24) ** Command line: root=/dev/xvda1 lockd.nlm_tcpport=61053 lockd.nlm_udpport=61053 ipv6.disable=1 net.ifnames=0 xen_blkfront.max_queues=3 ** Tainted: W (512) * kernel issued warning ** Kernel log: [ 366.744374] traps: wget[3327] trap invalid opcode ip:7fcabc94fb0a sp:7fffdd212c80 error:0 in libgnutls.so.30.34.1[7fcabc837000+12f000] ** Model information ** Loaded modules: tls nft_chain_nat xt_MASQUERADE nf_nat ipt_REJECT nf_reject_ipv4 xt_owner xt_mac xt_conntrack nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 xt_multiport nft_limit xt_tcpudp xt_LOG nf_log_syslog xt_limit nft_compat nf_tables libcrc32c nfnetlink sunrpc binfmt_misc intel_rapl_msr intel_rapl_common intel_pmc_core_pltdrv intel_pmc_core ghash_clmulni_intel aesni_intel crypto_simd cryptd cfg80211 rfkill evdev pcspkr drm fuse configfs ip_tables x_tables autofs4 ext4 crc16 mbcache jbd2 crc32c_generic tun xen_netfront xen_blkfront crct10dif_pclmul crct10dif_common crc32_pclmul crc32c_intel ** PCI devices: ** USB devices: not available -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.19.0-2-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages linux-image-5.19.0-2-amd64 depends on: ii initramfs-tools [linux-initramfs-tool] 0.142 ii kmod 30+20220630-3 ii linux-base 4.9 Versions of packages linux-image-5.19.0-2-amd64 recommends: ii apparmor 3.0.7-1 ii firmware-linux-free 20200122-1 Versions of packages linux-image-5.19.0-2-amd64 suggests: pn debian-kernel-handbook <none> pn grub-pc | grub-efi-amd64 | extlinux <none> pn linux-doc-5.19 <none> Versions of packages linux-image-5.19.0-2-amd64 is related to: ii firmware-amd-graphics 20210818-1 pn firmware-atheros <none> pn firmware-bnx2 <none> pn firmware-bnx2x <none> pn firmware-brcm80211 <none> pn firmware-cavium <none> pn firmware-intel-sound <none> pn firmware-intelwimax <none> pn firmware-ipw2x00 <none> pn firmware-ivtv <none> pn firmware-iwlwifi <none> pn firmware-libertas <none> ii firmware-linux-nonfree 20210818-1 ii firmware-misc-nonfree 20210818-1 pn firmware-myricom <none> pn firmware-netxen <none> pn firmware-qlogic <none> pn firmware-realtek <none> pn firmware-samsung <none> pn firmware-siano <none> pn firmware-ti-connectivity <none> pn xen-hypervisor <none> -- no debconf information
